Renesas ISL97519 | Demoboard EU-190 Water Sensor

HS4003

Overview

TopologySensors
Input voltage1.8-5.5 V
IC revision1

Description

This smart water sensor is ideal for situations where there is no Wi-Fi infrastructure available. The sensor effectively detects humidity levels and water spillage, promptly notifying the operator through LTE or NB-IoT. Additionally, it can even automatically trigger shut-off valves. This sensor is specifically designed for remote and self-sustaining buildings. It can also be used for remote watering of plants or agriculture in solitary areas that only have long-range connectivity infrastructure.

Features

Monitoring of autonomous, self-sustaining buildings/infrastructure.LTE-M/NB-IoT enables operation almost anywhere (network coverage assumed).Solar power/rechargeable battery allows self-contained operation.Detection of inappropriately high/low moisture levels or water spillage.Indication to the user to shut on/off the water valve via the MQTT broker.Ultra-low power LTE/NB-IoT + Low IQ DC/DC allows long operation/standby time.Works perfectly aligned with the smart water actuator.
