DRAGINO SN50v3 NB IoT Sensor Node with BLE 5.1 and Ultra Low Power MCU

Imagine a sensor that can stay awake for years while sending precise data over the best network available. The SN50v3 NB IoT Sensor Node with BLE 5.1 and Ultra Low Power MCU is that device. It is built for remote monitoring, smart agriculture, and industrial asset tracking. If you struggle with batteries that die after weeks or unreliable cellular links, this node solves both problems in one compact package.

DRAGINO SN50v3 NB IoT Sensor Node with BLE 5.1 and Ultra Low Power MCU

Many IoT projects fail because the sensor cannot reach a stable network and because power consumption forces frequent battery changes. That matters to you because downtime means lost data and higher maintenance costs. The SN50v3 combines NB-IoT connectivity for long-range, low-bandwidth links with BLE 5.1 for local configuration and OTA updates. Its 48 MHz ARM MCU, 256 KB flash and ultra-low sleep current let the device run for years on a single 8500 mAh Li/SOCl battery, giving you reliable data without the hassle.

Benefits

• Years of operation on one battery reduces maintenance visits.
• NB-IoT ensures coverage even in remote or underground locations.
• BLE 5.1 lets you configure the node quickly with a smartphone.
• Ultra-low sleep current (14 A) saves power while waiting for events.
• Multiple digital I/O pins support a range of sensors and actuators.

Usages

The SN50v3 fits in smart farms to monitor soil moisture, temperature and fertilizer levels, sending data back to a cloud dashboard via NB-IoT. In factories it can track machine vibration or temperature, alerting maintenance teams before a failure occurs. City planners use it for air-quality stations that need long-term, low-maintenance operation. It also works in wildlife tracking where a small, long-lasting node can be attached to a collar and report location through the cellular network.
