Sensors & Detectors
Measure temperature, detect gas leaks, sense motion, and monitor electrical loads with Wirelays sensors and detectors. Every sensor in this collection is tested, documented, and ready to integrate with Arduino, ESP32, Raspberry Pi, and other popular platforms.
Our sensor range covers the most common measurement needs in IoT, home automation, and industrial monitoring:
- MQ gas sensors (MQ-2, MQ-135, MQ-7) — detect LPG, smoke, CO, ammonia, and air quality levels
- DS18B20 waterproof temperature probes — stainless-steel, one-wire digital output, ideal for water tanks, HVAC, and cold-chain monitoring
- PIR motion sensors (HC-SR501) — passive infrared detection for security, lighting automation, and occupancy sensing
- Current transformer sensors (SCT-013) — non-invasive AC current measurement for energy monitoring and load detection
- Voltage transformers — step-down AC voltage sensing for power metering projects
Each sensor listing includes pinout diagrams, operating voltage, and sample wiring instructions so you can go from unboxing to working prototype quickly. Whether you are building a gas sensor alert system for your kitchen or a temperature sensor network for a cold storage facility, Wirelays has the parts you need. All products ship across India with technical support from Wirelays.
