Wireless Nixie Thermometer

Wireless Nixie Thermometer

The Target of this Project was to learn how to use different functions of the atmega:

• Connecting two Atmegas with a wireless connection
• Each Atmega has a Thermometer (DS1621) to read the actual temperature
• Use the sleep Mode of an Atmega
• Controlling a Nixie bargraph In-13

And this all together is a nice looking self-made Thermometer. The SPI interface is used to communicate with microcontroller for parameter setting.

Important features of the Module:

• Automatic antenna tuning

• Low costing, high performance and price ratio

• 2.2V – 3.8V power supply

• Standby current less than 0.3uA

• 16 bit RX Data FIFO

• You can sent/receive with the same module

• It cost 4-5€ each module


At Pollin you can also download programming examples!

A Nixie tube, or cold cathode display, is an electronic device for displaying numerals or other information using glow discharge.

The IN-13 Nixie Tube is a bargraph.

• Voltage: 150V
• Length: ca 120mm

Here you can find a very good test about the Nixie Tube:

DS1621 Thermometer

The DS1621 Digital Thermometer and Thermostat provides 9-bit temperature readings, which indicate the temperature of the device.

Temperature settings and temperature readings are all communicated to/from the DS1621 over a simple 2-wire serial interface.The scale is made by the company schaeffer: https://www.schaeffer-ag.de9/produkte/frontplatten/…

There you can dowload a programm to create your own CAD-Drawings.

Very cool is that you can after drawing generate the cost of the product.

One Scale costs about 50€.

> It is not very cheap but at the end it is a very good product.

At my scale I insertet at one side the Celsius and at the other Fahrenheit. At the top you can read if it is the internal or the outside temperature.
