AnaSonde KIT

  • Series AnaSonde-3M Kit
The AnaSondeTM family of digital radiosondes has been developed as a low-cost, user-friendly means of gathering scientific measurements in the lower atmosphere up to altitudes of approximately 30, 000 feet. AnaSondes feature a modular sensor suite that can be customized by the user, including simple interfaces for user-added sensors. Digital data is transmitted as decimal numbers to the ground in Morse code format. Presently, all AnaSondes operate in the 70-cm amateur radio band, and an amateur radio license is required to use them. AnaSonde signals are received using inexpensive amateur radio receivers which must be capable of receiving continuous-wave (CW) transmissions.

Technical Details.

The AnaSonde-3M is a multipurpose variant of the AnaSonde-3 family. As compared to the AnaSonde-3E, one major change is an increase in the number of analog channels from two to seven. This radiosonde features seven 10-bit analog-to-digital converter channels with 0-5 volt DC inputs (referenced to the regulated 5 volt supply voltage) and one frequency-counting channel which measures frequencies up to 25 kHz with 1 Hz resolution. A 10 milliwatt CW transmitter at approximately 434 MHz transmits data at regular intervals. With pressure, temperature, and humidity sensors (as pictured on the right), it has a mass of 15.0 grams. The circuit board is 0.85 x 3.25 inches.

There are two other major enhancements found in the AnaSonde-3M as compared to the AnaSonde-3E. First, the AnaSonde-3M is inherently capable of both Morse code and ASCII output the output mode is selected by the user during configuration. Second, the AnaSonde-3M has a secondary configuration mode which makes it particularly easy to enter callsigns as compared to the standard configuration mode (presuming one is manually entering the configuration without using the associated software).

Items Supplied With Each AnaSonde-3M.

The AnaSonde-3M can be ordered as a kit or pre-assembled. Every AnaSonde comes complete with everything needed for flight except for a 9-volt battery and helium for the provided balloon. Sensors specified by the user are included with the kit. Pressure, temperature, and humidity sensors are all available as standard options; resistive sensors for specialized measurements are available from Anasphere as well.

Additional equipment.

A serial interface cable is needed to use a PC to program the sonde configuration. A connector kit can be used to build custom cables for communications and external power supplies.

Ana Sonde-E Kit

The AnaSondeTM family of digital radiosondes has been developed as a low-cost, user-friendly means of gathering scientific measurements in the lower atmosphere up to altitudes of approximately 30, 000 feet. AnaSondes feature a modular sensor suite that can be customized by the user, including simple interfaces for user-added sensors. Digital data is encoded as hexadecimal values for transmission to the ground as either a series of tones or Morse code. Presently, all AnaSondes operate in the 70-cm amateur radio band, and an amateur radio license is required to use them. AnaSonde signals are received using inexpensive amateur radio receivers.

Technical Details.

The AnaSonde-E represents the most economical variant of the AnaSonde family. This radiosonde features two 10-bit analog-to-digital converter channels with 0-5 volt DC inputs (referenced to the regulated 5 volt supply voltage) and one frequency-counting channel which measures frequencies up to 25 kHz with 1 Hz resolution. A 10 milliwatt AM transmitter at approximately 434 MHz transmits data at regular intervals. With pressure and temperature sensors (as pictured on the right), it has a mass of 13.1 grams. The circuit board is 0.85 x 2.5 inches.

Morse Code Option.

The AnaSonde-E can be configured to transmit its measurements entirely via Morse code. Users with Morse code skills can receive telemetry by ear! Alternatively, a shareware program can be downloaded to decode the transmissions. A companion piece of software developed by Anasphere allows the user to seamlessly process the data as it is received. However, users will find that decoding by ear will yield the best results for long range work this can lead to a fun contest for your ham radio club!

AnaSonde Blink-E Kit

The AnaSonde Blink-ETM and Buzz-ETM are variants of the basic AnaSonde-ETM, Anasphere's original low-cost radiosonde for making meteorological measurements in the lower atmosphere. The Blink-E and Buzz-E are very low-cost measurement devices optimized for use in the classroom and student laboratory. They also provide an excellent introduction to the fundamental features and capabilities of the AnaSonde radiosondes, without requiring the user to have any special skill or additional materials - the kit and a 9-volt battery are all you need to start making measurements and enter the world of AnaSondes!

The Blink-E and Buzz-E are both based on a standard AnaSonde-E radiosonde circuit board. Each type measures temperature using an on-board temperature sensor. An on-board microcontroller takes the raw measurement from the sensor and converts it to a temperature in degrees Celsius. This number is then presented to the user via an on-board LED (Blink-E and Buzz-E) and can also be presented via an on-board speaker (Buzz-E only). The number is presented either in Morse Code or as a countable number of blinks or buzzes.

This method of data presentation is useful in several ways. First, for those intending to move on to more advanced versions of AnaSondes, this technique provides an introduction to how the AnaSondes can transmit data over radios. It also provides an introduction to how numbers are presented by audio methods, and it is an easy step to go from listening to the data from a Buzz-E to listening to the Morse code transmissions from the more advanced AnaSondes.

The data presentation methods are also of use in special-needs classrooms for blind or deaf students. Yes, even blind students have built AnaSondes from specially modified kits!

Technical Details.

The AnaSonde Blink-E and Buzz-E are based on the AnaSonde-E radiosonde. While the Blink-E and Buzz-E inherently have the full capability of the AnaSonde-E, at the present time we only offer the temperature measurement as a standard option, as the goal for these sensors is to provide the simplest possible introduction to the world of AnaSondes. Inclusion of other sensors (see optional configurations on the AnaSonde-E page) is possible upon request. The temperature measurement has a 1 degree Celsius resolution. The circuit board is 0.85 x 2.5 inches.

Data Output.

The data is presented to the user via an on-board LED (see the Buzz-E for an audio output option). The number is presented as a series of blinks of the LED. The number is presented either in Morse Code or as a countable number of blinks or buzzes. In the latter case, the numbers 1-9 are simply presented as the corresponding number of blinks; a special blink pattern indicates the digit zero, and another special pattern indicates a negative sign for temperatures below zero.

There is no need for any associated software or other devices to receive data from the AnaSonde Blink-E.

Supercooled Liquid Water Content Sensor

The Supercooled Liquid Water Content (SLWC) sensor is a device which can be used to measure the supercooled liquid water content of clouds. The sensor operates by measuring the buildup of ice on a thin vibrating wire. The mass of the ice changes the vibration frequency of the wire. The rate of change of vibration frequency can be used to quantitatively determine the supercooled liquid water content of the cloud. The SLWC sensor is designed to pair with any radiosonde capable of accepting the XDATA digital data format. The vibration frequency of the wire is reported to 0.02 Hz every 3 seconds.

AnaSonde-3 Programming Cable

This cable connects an AnaSonde-3 to your PC serial port for programming the AnaSondes configuration. It can also be used to receive serial data from the AnaSonde-3E ASCII or AnaSonde-3M. The cable does NOT supply 5 volts DC to the sonde; the sonde will require its own separate power.

Spectra Sonde Kit

The SpectraSonde is derived from the AnaSonde Buzz-E, which is used for surface-based measurements only. It is ideal for users who want the simplicity and low cost of the Buzz-E but need a wider variety of sensors or data output formats. The circuit board is also slightly larger than the Buzz-E, to facilitate a very clear parts layout, wide spacing of parts, and easier placement of the sensors into test chambers and the like.

The SpectraSonde is designed to measure temperature, pressure and relative humidity or any subset of those quantities. The data output format is switchable between Morse code or count-the-blinks (or count-the-beeps). Both audio and visual outputs are provided.
