data logger wireless

The input channels accept vibrating wire, 4–20 mA, 0–5 V, potentiometer, thermistor, and SDI-12 sensors. Digital ports handle RS-485 and TTL devices. Most geotechnical instruments—piezometers, inclinometers, extensometers, load cells—connect without additional signal conditioners.

Runtime depends on the logging interval and how many sensors are read. At a 15-minute logging rate, a typical setup with four sensors runs for about 18 months on a 12 Ah lead-acid battery. Deeper sleep modes and solar panels extend that significantly. We can estimate life for your specific sensor list and schedule.

Yes, almost all parameters are adjustable remotely. Sampling rate, alarm thresholds, sensor excitation voltage, and even which channels are active can be reconfigured through the web interface or over SMS commands. This lets you adjust monitoring intensity during critical phases without sending a technician to the site.

Current models support 4G/3G/2G cellular with automatic fallback, LoRaWAN, and, in some configurations, NB-IoT. Data is typically pushed to an FTP server, MQTT broker, or HTTP endpoint. Network selection depends on coverage at your site; we help choose the right variant during order configuration.

Yes, all network traffic uses TLS encryption (for TCP-based protocols) or LoRaWAN’s built-in AES-128 encryption. The logger also stores a local copy of all records, so if a transmission fails, no data is lost. Access to the configuration interface is password-protected and can be restricted to specific IP ranges.
