NTC Thermistor temperature sensor module is low cost, small size module. It is very sensitive to ambient temperature. It is generally used to detect the temperature of the surrounding environment. Through potentiometer adjustment, it is possible to change the temperature detection threshold.
DO output can be directly connected to the microcontroller to detect high and low, by detecting temperature changes in the environment. The temperature detection range of the module is between 20 and 80 degrees Celsius. This module can be replaced with a line temperature sensor for controlling the water temperature, water tank, etc.
Generally, the 4 wire method of thermistor measurement is the most accurate because there is effectively no current flowing in either of the measurement cable wires and therefore no added resistance due to the cable wires.
- Adopt the NTC thermistor sensor, sensitivity is good.
- The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma.
- With potentiometer to adjust the temperature detection threshold.
- Working voltage: 3.3 V to 5 V.
- Output form: digital switch output (0 and 1).
- It has a fixed bolt hole, convenient installation.
- Using the LM393 wide voltage comparator.
- A thermistor module is sensitive to the environment temperature, are commonly used to detect the temperature of the surrounding environment.
- Through to the potentiometer adjustment, can change the temperature detection threshold (i.e., temperature control), such as the need to control the environment temperature is 50 degrees, while the module corresponding environmental temperature to the green light, the DO output high level, below the set temperature, the output high level, green light don’t.
- The DO output can be attached directly to the single-chip microcomputer, through a single-chip microcomputer to detect the high and low level, thus to detect the temperature of the environment change.
- The DO output can be directly driven by our relay module, which can form a temperature control switch and control related equipment operating temperature, also can connect the fan used for cooling, etc.
- The module of the temperature detection range of 20-80 degrees Celsius.
- This module can also be replaced with a line of a temperature sensor, used for water temperature, control of the water tank, etc.
