Solar-Powered NB-IoT Liquid Level Sensor for Water Pressure & Level Monitoring
The Dragino PS-NS-I5/GE is a professional NB-IoT liquid level pressure sensor designed for long-term remote monitoring of water pressure and liquid levels. As an immersion-type sensor with a 5-meter cable, it measures liquid level by detecting hydrostatic pressure and uploads the sensor data wirelessly via NB-IoT cellular networks to IoT servers and cloud platforms.
The PS-NS-I5/GE belongs to Dragino’s PS-NS series and is designed for industrial and environmental monitoring applications where reliable pressure or liquid level measurement is required. It is particularly suitable for water tanks, wells, reservoirs, rivers, irrigation systems and industrial water management systems.
The device supports multiple uplink protocols including MQTT, MQTTs, TCP, UDP and CoAP, ensuring compatibility with a wide range of IoT platforms. It also supports BLE configuration and OTA firmware upgrades, allowing easier deployment and maintenance.
Unlike battery-powered PS-NB models, the PS-NS series uses a solar panel combined with a 3000mAh Li-ion battery, making it ideal for long-term outdoor deployments with minimal maintenance. Its rugged IP66 waterproof enclosure ensures reliable operation in harsh environments.
