Yet another led strip switch with optical proximity sensor TCRT5000.
Very small foot print, low cost and rich capability.
Based on attiny85, source code in C.
- 9.6 x 29 mm, can be placed beside led strip;
- proximity sensor max work distance about 50mm;
- source voltage 12V;
- mosfet switch can control led strip with in series resistor up to 2A;
- switch on|off by short "press";
This board uses a supercapacitor rated at 5.5V which is intended to be charged by a solar cell rated at 6V. The moisture sensing is done by one of the cheap capacitive sensors. The ATtiny85 microcontroller firmware reads the moisture sensor every 30 seconds and blinks the LED if the measured value is over a threshold. The button is used to program the threshold.
