Product Overview

Description


Welcome to R.D.S Electronics 


 











Product Description

 



 



 

Features:


 





  • Using high-quality dual-panel design,with power indicator and TTL signal output instructions.




  • The switching signal having a DO (TTL) output and analog output AO.




  • TTL output valid signal is low. ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )




  • Analog output voltage with the higher concentration of higher voltage




  • There are four screw holes for easy positioning.




  • Has a long life and reliable stability




  • Rapid response and recovery characteristic




Input voltage : DC5V Power consumption ( current ): 150mA
DO output : TTL digital 0 and 1 ( 0.1 and 5V)
AO output :0.1-0 .3 V ( relative to pollution ),the maximum concentration of a voltage of about 4V
Special note: After the sensor is powered,needs to warm up around 20S,measured data was stable,heat sensor is a normal phenomenon,because the internal heating wire,if hot is not normal .

Wiring:





  • VCC: positive power supply (5V)




  • GND: power supply is negative




  • DO: TTL switching signal output





  • AO: analog signal output


    NOTE:


    After the sensor is powered, need to warm about 20S, measured data becomes stable, heat sensor is normal
