👤 PIR Unit – Human Body Infrared Sensor The PIR Unit is a compact passive pyroelectric infrared detector designed to sense infrared radiation emitted or reflected by human bodies and objects. When motion or presence is detected, the unit outputs a high signal for a short delay period (2 seconds), allowing repeated triggers until the signal disappears and returns to low. This module communicates with M5Core via the GROVE B interface, making it easy to integrate into automation, security, and smart home projects. ⚙️Features ✅ Detection distance: up to 500 cm ✅ Latency time: 2 seconds (supports repeated triggers) ✅ Sensing range: < 100° ✅ Low quiescent current: < 60 μA ✅ Operating temperature: –20 °C to +80 °C ✅ GROVE interface – compatible with UIFlow and Arduino ✅ Two LEGO installation holes for flexible mounting 📦 Package Contents 1 × PIR Unit 1 × GROVE Cable 🔧 Applications 💡 Human body induction lamps 🔒 Security products ⚙️ Automatic induction appliance settings 🏠 Smart home automation 📊 Technical Specifications Specification Parameters Detection Distance 500 cm Latency Time 2 s Sensing Range < 100° Quiescent Current < 60 μA Operating Temp. –20 °C to +80 °C Interface GROVE B Net Weight 5 g Gross Weight 20 g Product Size 32 × 24 × 12 mm Package Size 60 × 57 × 17 mm 🌍 Why Choose PIR Unit?
