Seeed Studio Studio Grove Mini PIR Motion Sensor v1.0 - 3.3V/5V, Adjustable Sensitivity, 2m Range
The Seeed Studio Studio Grove Mini PIR Motion Sensor v1.0 is a passive infrared (PIR) module designed for detecting human movement within a 2-meter range. Operating from 3.3V to 5V DC, it features an ultra-low 12–20 µA current draw and adjustable sensitivity, making it ideal for battery-powered Arduino, Raspberry Pi, and other microcontroller projects via the Grove connector system.
Features
- Ultra-Low Power Consumption: Operates at just 12–20 µA, ideal for battery-powered IoT and embedded systems.
- Adjustable Detection Sensitivity: Features a solder pad for a slide rheostat to fine-tune sensitivity from 120 to 530 µV.
- Grove System Compatibility: Plug-and-play connectivity with Seeed Studio Studio Grove Base Shields for rapid prototyping.
- Compact Form Factor: Measures only 24mm x 20mm, with a lightweight 8g design for space-constrained applications.
- Wide Operating Voltage: Compatible with both 3.3V and 5V logic systems commonly used with Arduino, ESP32, and Raspberry Pi.

The Grove Mini PIR Motion Sensor utilizes a passive infrared (PIR) sensing element (S16-L221D chip) to detect changes in infrared radiation emitted by moving objects, primarily humans, within its field of view. It outputs a digital HIGH signal on its SIG pin upon detection, providing a simple trigger for control systems. The sensor’s sensitivity can be mechanically adjusted by repositioning its Fresnel lens cap or electronically via an optional soldered rheostat.
Engineered for reliability in indoor environments, the sensor performs optimally at 25°C with a recommended detection distance of up to 2 meters. Its low-power design and Grove interface simplify integration into security systems, automated lighting controls, and presence monitoring applications, requiring minimal signal conditioning.
