AM312 Mini Pyroelectric PIR Sensor Module Manual Motion Infrared IR Detector SR301
The PIR AM312 detects both people and movements within rooms using infrared detection. The AM312 PIR sensor allows a power supply of 2.7 to 12V and is ideal for operation in combination with 3.3V based modules such as ESP8266, ESP8285, ESP32, STM, etc.
Feature:
- Based on passive body infrared technology digital intelligent automatic control products, high sensitivity, reliability
- Low power consumption, small size, easy to install.
- Internal use of digital signal processing, pit interference strong.
- Repeatable trigger mode: that is, after the induction output is high, in the delay period, if the body in its induction range of activities, the output will remain high until the delay after the person to become Low level. (Ie, the sensing module automatically detects a delay period after each activity of the human body, and takes the last active time as the starting point for the delay time).
Technical parameters:
- 1. Working voltage: DC 2.7-12V;
- 2. Static power consumption: <0.1mA;
- 3. Delay time: 2 seconds;
- 4. Blocking time: 2 seconds;
- 5. Trigger mode: repeatable;
- 6. Sensing range: ≤100 degree cone angle, 3-5 meters; (depending on the specific lens)
- 7. Working temperature: -20 - +60 °C;
- 8.PCB dimensions: 10mm*8mm;
- 9. Module lens: small lens
Application:
- Widely used in various types of automatic induction electrical equipment.
