I am looking for a Wi-Fi–enabled dual-stage temperature controller. When the temperature falls below the set point, a 12 V heater along with 12 V DC Fan #1 turns ON, based on the signal received from Temperature Probe #1. If the temperature measured by Temperature Probe #2 exceeds its set point, 12 V DC Cooling Fan #2 turns ON.
I only need a PCB board with power circuit block terminals to connect:
1 × 12 V heater
2 × 12 V DC fans
2 × temperature sensors
wifi is not important at this moment ,
