2. there are four screw holes for easy positioning
3. Analog output voltage with the higher concentration of higher voltage
4. TTL output valid signal is low. (Low-level signal when the output light can be directly connected to the microcontroller or relay module)
5. The switching signal having a ... DO (TTL) output and analog output AO
Special note:
After the sensor is powered, needs wait about 20S, measured data was stable, heat sensor is a normal phenomenon, because the internal heating wire.
