The MOCREO ST4 system utilizes a star-topology network with a 433MHz Sub-1GHz radio link between the sensor nodes and a central gateway. This frequency selection provides superior signal penetration through commercial-grade stainless steel and thick insulation compared to 2.4GHz protocols. Each sensor node incorporates a digital thermistor with a verified accuracy of ±0.5°C, housed in a water-resistant chassis powered by a single CR2450 cell.
Performance data confirms a battery lifespan of 12 to 24 months, achieved by offloading high-power Wi-Fi tasks to a wall-powered central hub. The hub manages the 2.4GHz Wi-Fi uplink for cloud-based email and push notifications. Aggregated specification data lists support for up to 10 sensors per gateway, allowing for scalable multi-point monitoring within a single facility. Manual offsets are available via the software interface to align the digital output with local thermal mass variances.
To ensure redundant safety monitoring in the event of a gateway failure, deploying these units alongside alarm system sensors provides a multi-layered detection strategy. If your application requires a submersible probe for liquid monitoring rather than ambient air sensing, the MOCREO Smart Temperature Sensor with Probe is the recommended alternative configuration. This system is a primary example of specialized hardware in the freeze/temp sensors class.
