I propose to discuss the following development: touch switch with glass panel battery operated. Now the development is at the stage of software testing. The prototype is ready, the energy consumption tests have been successfully passed. The estimated time of operation with an led that is constantly working 9-12(maybe longer | ??? ) months, without led, only with a buzzer that simulates the click of the relay-2-3 years. Device height 7mm, Board dimensions 42mm X 42mm. This touchpad can works in master slave mode with my other device
Video1: test
Video2: check the interaction with another device, master-slave mode
Video3: check the interaction with another device, master-slave mode 2
- On Board the device are:
- Glass panel 47mm X 47mm
- Atmega328
- 8MHz crystal oscillator (for DIY)
- tp223
- three-color led
- photoresistor
- nrf24l01
- AT25F512B-SSH-T (flash)
- ATSHA204A_SOT23 (cripto)
- buzzer
- XC6206P332 (consumption of 1 µa)
- two cr2430 batteries (6v)
- FTDI (micro)
- ICSP (micro)
Works with all bootloaders
