RAINdot

Feature and Application

Introduction

RAINdot is a rainfall datalogger that utilizes the latest NB-IoT wireless transmission technology to measure the pulse count signal from the rain gauge. This datalogger features a sturdy, waterproof enclosure and a low power consumption design. It is powered by two 18650 lithium-ion batteries and offers long-term measurement and data upload to the dot cloud platform, with an additional 5-18 VDC charging function. Furthermore, the built-in 32 GB Micro SD card is capable of storing over 1 million data entries. RAINdot is also compatible with various rain gauge devices, enhancing its versatility for different applications. RAINdot is suitable for rainfall monitoring in urban civil engineering projects, river and water conservancy projects, bridge engineering, and slope safety monitoring.

Applications

Key Features

Low-Power Consumption

NB-IoT Wireless Transmission

Powered by two 18650 Li-ion rechargeable battery, it is able to be stand-alone for at least 8 months if RSSI <15; 16 months if RSSI ≧15. (Based on measuring once per hour)

Uploading data to the cloud by complying with latest NB-IoT wireless transmission technology for real-time monitoring

Real-time Cloud Monitoring

MQTT Protocol

Recorded data can be uploaded to cloud service for 24-hour real-time monitoring through simple set-ups on the SD card

Complied with MQTT protocol, it is easy to receive and integrate various data
