LoRaWAN Class A soil sensor measuring temperature, moisture, and electrical conductivity with up to 10 km range and 3-year battery life

The LoRaWAN Wireless Soil Sensor KM-S8 is a rugged, IP66-rated precision agriculture instrument that simultaneously measures soil temperature, volumetric water content, and electrical conductivity (EC) — three critical indicators of soil health that directly impact crop yield, nutrient availability, and microbial activity. Built on the Wio-E5 LoRaWAN processor with Class A v1.0.3 protocol compliance, it delivers reliable long-range data transmission up to 10 km with -136dBm receiver sensitivity and 19dBm transmit power across CN470 and other regional frequency bands. A built-in Bluetooth interface enables rapid field configuration via smartphone app without specialized tools or programming, while the 19Ah D-cell lithium battery provides 1 to 3 years of maintenance-free operation depending on sampling frequency. Designed for digital agriculture deployments, scientific research stations, and greenhouse and facility farming operations, the KM-S8 replaces manual soil sampling with continuous, remote-accessible data streams that enable data-driven irrigation scheduling, salinity management, and fertilization optimization.

Sub-GHz micro-power wireless temperature & humidity sensor with LCD, on-device threshold alarms, 5+ km line-of-sight range, and 5-year battery life

This micro-power wireless temperature and humidity sensor is an install-and-use industrial sensing node with a built-in LCD, designed for large-scale environmental data acquisition where wiring is impractical and battery replacement must be rare. It measures ambient temperature with ±0.5°C accuracy across 0–80°C (±2°C from -40 to 0°C) and relative humidity to within ±3%, sampling on a configurable 5-to-240-minute cycle and transmitting over a sub-GHz radio link (476.505 / 488.505 MHz, frequency customizable) with over 5 km line-of-sight range. The device auto-registers to a concentrator and auto-routes through repeaters, forming self-organizing wireless networks that scale from a single room to a full industrial site, then delivering centralized, multi-mode data output. A five-button front panel with LCD backlight lets field technicians set the real-time clock and configure temperature and humidity upper/lower limits and alarm return (hysteresis) values directly on the unit for over-threshold alerting — no PC or app required. Powered by an internal battery with 10±0.5μA static sleep current, it delivers more than 5 years of maintenance-free operation (roughly 1 year at a 5-minute sampling interval, 5 years at 30 minutes), making it well suited to environmental and meteorological monitoring, healthcare, energy and chemical plants, warehousing and transport, cold-chain storage, production workshops, and general industrial-site monitoring.

Integrated wireless temperature transmitter with ±0.5°C accuracy, >500m range, <15μA average current, and 5-year replaceable-battery life

This micro-power wireless temperature transmitter is an integrated, all-in-one sensing node that combines a temperature probe, sub-GHz radio, and long-life battery in a single housing — purpose-built for wireless temperature acquisition where running signal or power cables is impractical. It measures ambient temperature across -40 to 80°C with ±0.5°C accuracy and transmits ASCII data frames over a configurable sub-GHz link (default 433 MHz, with 868 / 915 MHz available), reaching more than 500 m line-of-sight with <10 dBm transmit power and <-112 dBm receiver sensitivity. Drawing just 15 μA average current, it runs for more than 5 years on a single replaceable ER14250 3.6V lithium-thionyl-chloride cell (1000 mAh class) within a 2.5–3.6V operating window, eliminating per-point wiring and frequent maintenance. Its self-contained, industrial-grade design suits cold-chain and refrigerated storage, factory and workshop monitoring, environmental and outdoor sensing, and any remote or distributed point that needs reliable, low-power temperature telemetry.
