This is a cheap ultra low power board designed to receive up to 3 sensors. It runs on an ATTiny84 microcontroller which can be programmed via ISP (2x3 pads exposed).
Can connect almost every cheap Chinese sensor + battery friendly ;)
Compatible, Ultra low power, Hackable. It is compatible with many sensors, but you have to write your own code for it. When it does nothing, every peripheral can be powered down. Thus it consumes less than 6µA when asleep --> 1.2 years one a single coin cell (CR2032).
If you want fully working sensor kit, please go to check my "433 Sensor kit".
This is for advanced users only! You must know how to flash an ATTiny before use, but I personally learned quite quickly as it is Arduino compatible :)
Programming note : The CKDIV8 fuse is activated by default on a new microcontroller, I strongly suggest that you read the fuses before flashing them with AVRDUDESS.exe for example.
