Basic Thermostat
This project implements a basic temperature control system from a 3 modules MyDin made of:
- DINCASE-MB3PICO : controler based on Raspberry-Pi Pico
- DINCASE-2R-BP3MOD : 2 relays backplane
- TMP-DS18B20-WP : a DS18B20 OneWire temperature sensor.
The temperature sensor takes the room temperature and the heater is controled by the relay 1.
- * DS18B20 is connected to 1Wire port
- * Rel 1 control the Heater
- * LED 1 reflect the Rel 1 state.
- * Button 1 invert (force) the state of the relay.
- * Forced state is canceled with the thermostat state reach the forced state
- * Forced state is canceled when the button 2 is pressed.
- * LED2 is lit while a forced state do applies
- * button 3 will decrease the setpoint T°. Led 3 will blick once to acknowledge.
- * button 4 will increase the setpoint T°. Led 4 will blink once to acknowledge.
