Water Level Sensor

Make : EnthuTech
Brand: ETS
Model: ETS-3WL-S

Product Overview:

The ETS-3WL-S is a LoRaWAN Distance Detection Sensor used to measure the Water Level in the tanks. This measurement uses ultrasonic sensing technology for water level measurement, and temperature compensation is performed internally to improve the reliability of data. It uses LoRaWAN wireless technology to send the
data to IoT Server. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

ETS-3WL-S supports BLE configure and wireless OTA update which
make user easy to use. It is powered by Solar panel + 3000mAh Li-Ion battery or 230VAC + 2600 mAh Li-Ion Battery or 8500mAh Li/SOCl2 Battery. The Image Shown above may vary based on Power Source selection.

This has option to connect upto 3 Ultrasonic type Sensors in one Transmitting device. User can select based on site conditions.
