The AZDelivery SR312 is a miniature smart PIR motion sensor based on passive infrared technology that reliably detects movement. With its compact design (only 30 x 14 x 14 mm), the sensor is ideal for applications with limited space – perfect for Arduino, ESP32, and Raspberry Pi projects as well as smart home and security solutions. The sensor operates with a supply voltage of 2.7 to 12 V DC and has a low power consumption of less than 100 mA. Thanks to its wide detection angle of 100° and a range of up to 5 meters, the motion sensor precisely detects thermal changes in the room. The digital output remains active for approx. 2 seconds after motion detection and triggers repeatedly in case of continuous motion – ideal for automatic lighting control, alarm systems, or presence detection. The SR312 is an alternative to HC-SR501 and AM312 sensors and can be combined with LDR sensors, light barriers, ultrasonic sensors, and other Arduino components. Connection is convenient via standard Dupont cables. https://elecena.pl/product/29841254/sr312-mini-pir-motion-sensor-12v-infrared-ir-sensor-module-for-arduino-2-7-12v-100-detection-5m-range-compact-motion-dete 2026-02-17 https://elecena.pl/product/29841254/sr312-mini-pir-motion-sensor-12v-infrared-ir-sensor-module-for-arduino-2-7-12v-100-detection-5m-range-compact-motion-dete 2026-02-21 https://elecena.pl/product/29841254/sr312-mini-pir-motion-sensor-12v-infrared-ir-sensor-module-for-arduino-2-7-12v-100-detection-5m-range-compact-motion-dete 2026-02-23 https://elecena.pl/product/29841254/sr312-mini-pir-motion-sensor-12v-infrared-ir-sensor-module-for-arduino-2-7-12v-100-detection-5m-range-compact-motion-dete 2026-06-02 https://elecena.pl/product/29841254/sr312-mini-pir-motion-sensor-12v-infrared-ir-sensor-module-for-arduino-2-7-12v-100-detection-5m-range-compact-motion-dete 2026-08-15 https://elecena.pl/product/29841254/sr312-mini-pir-motion-sensor-12v-infrared-ir-sensor-module-for-arduino-2-7-12v-100-detection-5m-range-compact-motion-dete 2026-08-29
