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.

Sub-GHz wireless sensor concentrator with 4G LTE cellular backhaul, -136dBm sensitivity, 5km range, auto-routing, and 4-channel relay control — works anywhere with cellular coverage, no Ethernet wiring required

This 4G IoT Gateway is a SIM-card-based data concentrator that bridges battery-powered sub-GHz sensor nodes to a cloud backend without any on-site network infrastructure. It aggregates measurements from wireless sensors over a 470 MHz radio link (frequency customizable) with -136 dBm receive sensitivity and more than 5 km line-of-sight range, then forwards the data to a backend server over a 4G LTE cellular connection — no Ethernet cabling, no local broadband provisioning, just power and a SIM card. The gateway auto-routes traffic through repeaters to extend coverage across obstructed or large sites and connects through the cellular network regardless of whether the deployment site has its own Internet access. Beyond data collection, it acts as a network controller: it wirelessly configures sensor parameters such as sampling interval and auto-report, synchronizes node clocks, sets node geolocation, and drives 4-channel relay terminals for open/close and timed control via documented command frames. Configuration is handled through a browser console accessible over the cellular link — set the remote server IP, port, or domain, manage APN and cellular network settings, and log in to monitor the device; a reset button restores factory defaults. Powered by an external 5V DC supply, housed in a 110 × 80 × 26 mm enclosure, and rated for -40 to 80°C, it untethers environmental monitoring from wired networks — ideal for remote meteorological stations, scattered cold-chain sites, off-grid energy facilities, roadside storage, and any distributed deployment where pulling Ethernet cable or provisioning local broadband is impractical.
