Seconsor controlled relay to be used for pump, main switch etc. S1 switch to be replace by magnetic water sensor (sump), photocell etc. For sump (drain pump) a timer might be needed to delay the start. This depends on the lenght of the sensor.
STM32 RGB generic control module (the one found on the cheap online retailers). Paths and some parts may not be accurate as they do vary, but the schematic was recreated based on the P9813 datasheet for the +12V power source. Note that this chip takes in power from 9V all the way up to 30V or so (check datasheet for specifics), and that the paths/chip locations are not perfectly representative of...
Aim : To design PIC16F877A based Temperature controller, LM35 as Temperature Sensor, A pot reference set point adjustment. LCD to display Current Temperature, Reference Temperature and status of the output.
Software : MPLAB IDE.
Code : Assembly language(under development...).
