Overview

TopologySensors
Input voltage1.8-5.5 V
IC revision1

Description

When the wireless smart water sensor detects excessive moisture levels or water spillage, this shutdown valve system can automatically take countermeasures without human intervention, even in the absence of a Wi-Fi infrastructure. This feature is especially beneficial for remote and self-sustaining buildings and infrastructure, preventing damage caused by broken pipes through water supply shutdown. Additionally, it facilitates the remote watering of plants, agriculture, and horticulture.

Features

LTE/NB-IoT enables water supply shutdown, ensuring seamless integration with the smart water sensor.Solar power/rechargeable battery allows self-contained operation, even without the main power or during brownout conditions.LTE-M/NB-IoT enables operation almost anywhere (network coverage assumed).High/low moisture levels or water spillage can be indicated through an LTE sensor or by manual command via MQTT.Ultra-low power LTE/NB-IoT + Low IQ DC/DC allows long operation/standby time.Ideal for autonomous, self-sustaining infrastructure/buildings.

Typical applications

  • Smart Actuators, Smart Sensors
