temperature data logger wireless

A wireless temperature data logger typically records from one or more sensor channels and transmits readings to a receiver or cloud. When comparing units, check supported sensor types: many industrial loggers work with Type K, T, or J thermocouples, and some also accept Pt100 RTDs. Input range and accuracy depend on the internal analog‑to‑digital converter; 16‑bit resolution is common in mid‑range devices, yielding ±0.5°C accuracy after calibration. Transmission frequency matters: 2.4 GHz offers higher data throughput but shorter range, while sub‑1 GHz bands (e.g., 868/915 MHz) penetrate walls better and can reach 300–500 meters line‑of‑sight. Battery life is tied to sampling rate and transmission interval—a logger set to report every minute will drain faster than one logging every 15 minutes. Many units store data locally as a backup, with onboard memory for thousands of points. Kingmach supplies loggers that support common industrial protocols like Modbus or simple CSV export via USB. For compatibility, check whether the receiver software can export to your existing monitoring platform; some brands use proprietary cloud dashboards, while others allow direct data push via MQTT or HTTP. Physical housing is another factor: IP65‑rated enclosures are typical for damp or dusty environments. Kingmach’s manufacturing background means they can adjust channel counts, sensor inputs, and even form factor for project‑specific needs. If your application involves geotechnical monitoring, you may also need a logger that integrates with other instruments like vibrating wire sensors; Kingmach’s in‑house expertise often extends to such mixed‑sensor setups.
