Product Features
  • High-quality dual-panel design, with power indicator and TTL signal output instructions
  • DO switch signal (TTL) output and AO analog signal output
  • TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller or relay module)
  • Analog output voltage, the higher the concentration the higher the voltage
  • Four screw holes for easy positioning
  • Reliable and stable
  • Rapid response and recovery characteristics

Product specifications
Input voltage DC 5V
Power (current) 150mA
DO output TTL digital 0 and 1 (0.1 and 5V)
AO output 0.1-0 .3 V (relatively clean), the highest concentration of voltage around 4V
Length 32 mm
Width 20 mm
Height 22 mm

Note

After the sensor is powered, please allow the device to warm up for at least 20 seconds. Once it is warmed, the measured data will be stable and the heat sensor will operate as normal.
