The module realizes precise linear linearity adjustment, realizes high and low level and load-driven dual output, which is convenient for front-end acquisition and single-chip switching. The module sensor can be connected to many sensors, such as: Resistive sensors: NTC type thermistor type temperature sensor, photoresistor type photosensor, vibration sensor, etc. Using Method:by reference voltage adjusting potentiometer to generate reference voltage,and compare voltage generated by sensor and divide resistor with reference voltage,achieving high/low level comparision result output. LM393 comparator chip, module input voltage is 4.5-28V, stable performance. Application: NTC thermosensitive temperature sensor, photosensitive sensor
