Manufacturer Product Number
M20
Description

4-pin 3-pin thermal sensor module

Package Condition
Bulk

Purpose

Temperature detection, temperature control sensor, environmental temperature detection

Module features

1. Adopting NTC thermistor sensor with good sensitivity

2. The comparator output has a clean signal, good waveform, and strong driving capability, exceeding 15mA.

3. Adjust the temperature detection threshold with a potentiometer

4. Working voltage 3.3V-5V

5. Output format: Digital switch output (0 and 1)

6. Equipped with fixed bolt holes for easy installation

7. Small PCB size: 3.2cm x 1.4cm

8. Using a wide voltage LM393 comparator

Module usage instructions

1. Thermistor modules are highly sensitive to environmental temperature and are generally used to detect the temperature of the surrounding environment;

2. By adjusting the potentiometer, the temperature detection threshold (i.e., the control temperature value) can be changed. If it is necessary to control the ambient temperature to 50 degrees, the module will turn on the green light when the corresponding ambient temperature is adjusted, and the DO will output a high level. When the temperature is lower than this set value, the module will output a high level and the green light will not turn on;

3. The DO output terminal can be directly connected to the microcontroller to detect high and low levels, thereby detecting temperature changes in the environment;

4. The DO output terminal can directly drive the relay module of our store, which can form a temperature control switch to control the working temperature of related equipment, and can also be connected to a fan for heat dissipation, etc;

5. The temperature detection range of this module is 20-80 degrees Celsius;

6. This module can also be replaced with a wired temperature sensor for controlling water temperature, water tank, etc.
