01. The switching signal having a DO (TTL) output and analog output AO ;
02. TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )
03. Analog output voltage with the higher concentration of higher voltage.
04. A gas, natural gas, city gas , smoke better sensitivity.
05. Has a long life and reliable stability
06. Rapid response and recovery characteristics
07. Input voltage : DC5V Power consumption ( current ): 150mA
08. DO output : TTL digital 0 and 1 ( 0.1 and 5V)
09. AO output :0.1-0 .3 V ( relative to pollution ) , the maximum 10. concentration of a voltage of about 4V
11. 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 .

Description
Heart rate data can be really useful whether you're designing an exercise routine, studying your activity or anxiety levels or just want your shirt to blink with your heart beat. The problem is that heart rate can be difficult to measure. Luckily, the Pulse Sensor Amped can solve that problem!
