TTL Signal Output Circuit Board Chip RDA223 Digital Pyroelectric Sensor

RDA223 Digital Pyroelectric Sensor Infrared human body sensor Electric infrared sensor

The RDA223 digital pyroelectric sensor integrates the sensitive element of the traditional pyroelectric sensor with the signal processing chip, and integrates the sensitive element and the IC chip into the sensor shielding cover. The sensitive element detects the infrared signal generated by the external human body movement. It is transmitted to the high-precision digital intelligent processing chip for processing by differential input. The signal processing is completed, and the sensor directly outputs digital signals for convenient use.

Sensor characteristics

1. High precision AD signal processing;

2. Differential signal input mode, strong anti-interference ability;

3. With sensitivity adjustment, delay time adjustment, photosensitive enable control function;

4. The enable end enables the sensor to turn on the output;

5. Low working voltage and low power consumption;

6. Digital TTL signal output.
