Digital RS485 Temp & Humidity Sensor – PE Waterproof Probe, -40°C to 80°C, Modbus RTU

Struggling to monitor temperature and humidity in harsh or remote environments? The amiciKart Digital RS485 Temp & Humidity Sensor gives you industrial-grade precision in a compact, waterproof package — ready to plug into any PLC, SCADA, or IoT system in minutes.

This sensor measures temperature across a wide -40°C to 80°C range with ±0.3°C accuracy, and humidity from 0–100% RH with ±3% RH accuracy — making it one of the most precise options available at this price point. The PE waterproof metal probe is built to withstand moisture, condensation, and outdoor exposure, so it performs reliably in greenhouses, cold storage rooms, server racks, outdoor electrical cabinets, and industrial automation setups. Communication happens over RS485 Modbus RTU — the gold standard for industrial data transmission — ensuring noise-free, long-distance signal integrity across your entire control network.

Setup is genuinely straightforward: the sensor ships with a 1-metre colour-coded cable (Red: V+, Black: GND, Yellow: 485-A, White: 485-B) and runs on just DC 2.1–3.6V, making it compatible with Raspberry Pi, Arduino, ESP32, and most embedded systems. Whether you're an automation engineer, a hobbyist building a smart greenhouse, or an IT admin monitoring a server room, this sensor slots right into your workflow.

Backed by a 1-year warranty and India-based support via WhatsApp, call, or email — amiciKart stands behind every unit. Free shipping across India, same-day dispatch for orders before 2 PM, and COD available. 🚀
