Custom DS18B20 Temperature Sensors for emonPi – Trusted by OpenEnergyMonitor (UK)

We design and manufacture high-performance, custom DS18B20 digital temperature sensors for real-world applications. Recently, we developed two specialized models tailored specifically for OpenEnergyMonitor’s flagship emonPi system, used across the UK and beyond for accurate temperature and energy monitoring.

Our DS18B20 Sensor Variants:

1. Stainless Steel Probe + Flat Telephone Cable + RJ45 Connector

– Custom pin definition based on client specifications for plug-and-play connection with RJ45 sensor hubs.

2. Stainless Steel Probe + PVC Cable + 3.5mm Jack Plug

– Perfectly compatible with emonPi input ports, offering robust and waterproof sensing performance.

These sensors are widely deployed in OpenEnergyMonitor.org projects – an open-source platform based in North Wales, UK that empowers users to monitor electricity, temperature, humidity, and pulse utility meters. Our temperature probes ensure accurate, real-time temperature readings, making them ideal for residential and commercial smart energy systems.
