or
- PERFECT USE FOR DOMESTIC APPLIACES: office machine, audio, equipment, automobile, etc. （Remote control TV receiver, monitor display, Audio Raspberry Pi equipment high rushing current use application).
- DIRECT CONTROL WITH: Raspberry, Arduino, AVR, PIC, DSP, ARM or TTL logic.
- ADDED IN OPTOCOUPLER: .The microcontroller doesn’t have a physical connection with the relay, it’s more efficient to use LED lights.
- MICROCONTROLLER FRIENDLY: To save your microcontroller from a high voltage for VAC/VDC use the LED light of the Optocoupler IC to activate the relay.
- TECHNOLOGICAL SPECS: Equipped with high-current relay: AC250V/110V - 30A ; DC30V 30A. For control of module need power 5V and logic operation 3.3V/5V.

Skip both of those sensors and get a BME280 sensor, instead. $7 on Amazon (or less if you buy more than one), works on I2C. And you get temp, humidity and barometric pressure in one easy to use sensor.
If you use it with an ESP32, be sure to keep the sensor away from the ESP itself. There have been numerous posts recently about the heat from the ESP affecting the readings of these temp sensors, especially if they're both in a small enclosure.
You'll need a relay, but be sure to get one that'll handle the current of a space heater. How many amps does that heater pull? Many of the arduino relay modules out there have 10A ratings. A 1500W heater is going to pull 12.5A, so I'd get something with more current handling capability. This optocoupler isolated, 30A relay would work, though. You can get 3 of them for $20 and have spares on hand if one kicks the bucket.
You could do simple control where the relay energizes at the low temp and de-energizes at the high temp, or you could look into using PID control. I'd start with the simple set method, then learn how to implement PID control once you have it working and want better control over temperature and energy usage.
