LoRaWAN Wireless Tipping Bucket Rain Gauge

Wireless rain sensor has a built-in LoRa wireless transmitter module. It measures precipitation as a terminal node and sends data to the gateway, which is then uploaded to the server. The sensor uses a three-dimensional streamlined integrated rotating bucket, which has smooth water transfer and self-cleaning dust and easy cleaning functions. It can be widely used for rain measurement in industrial environments such as weather stations.

Rain Gauge SN200-ABS25

Wireless tipping bucket rain gauge is a hydrological and meteorological instrument used to measure natural rainfall, and at the same time convert rainfall into digital information output in the form of a switch, to meet the needs of information transmission, processing, recording and display. It is a precision rain gauge, and the tipping bucket and the water outlet of the water diversion funnel must be regularly maintained and cleaned during use.

◀◀Working principle -LoRaWAN Wireless Tipping Bucket Rain Gauge ▶▶

Structure Diagram

The LoRaWAN wireless tipping bucket rain gauge integrates mechanical tipping technology with low-power LoRaWAN communication to realize accurate, remote rainfall monitoring. Its core mechanism consists of a collecting funnel, a balanced tipping bucket assembly, a magnetic sensing switch, and a LoRaWAN transceiver module.

When it rains, the funnel collects rainfall and guides it into one of the two symmetric bucket chambers. Each chamber is calibrated to hold a fixed volume of water, typically corresponding to 0.1mm or 0.2mm of rainfall. Once the water in the filled chamber reaches the preset volume, gravity causes the bucket to tip, emptying the water and switching the other chamber to the collection position.

During the tipping motion, a magnet attached to the bucket triggers a reed switch, generating one electrical pulse per tip. The device counts these pulses and aggregates data at regular intervals (usually 10 minutes). Equipped with AES-128 encryption, the LoRaWAN module transmits the pulse count, interval duration, and accumulated rainfall wirelessly over long distances with minimal power consumption. Users can retrieve real-time data via a cloud platform or private infrastructure, enabling reliable precipitation monitoring for meteorology, hydrology, and agriculture.

◀◀Functions -LoRaWAN Wireless Tipping Bucket Rain Gauge ▶▶

1. The tipping bucket rain sensor is used to measure natural rainfall, and convert rainfall into digital information output in the form of switch signals to meet the needs of information transmission, processing, recording and display.

2. The tipping bucket rain sensor is suitable for meteorological stations, hydrological stations, agriculture, forestry, national defense and other relevant departments to remotely measure liquid precipitation amount, precipitation intensity and the start and end time of precipitation.

3. It is used as a precipitation measuring sensor in hydrological automatic telemetry systems and automatic field telemetry stations for flood control, water supply scheduling and hydrological management of power station reservoirs.

◀◀Notes on Use -LoRaWAN Wireless Tipping Bucket Rain Gauge ▶▶

1. Regularly clean the rain inlet with a special cleaning pen for rain sensors to prevent blockage by debris.

2. When the instrument is placed indoors or used outdoors on confirmed rainless days, cover the inlet with the cylinder lid to prevent dust from entering the rain collector.

3. Frequently check the axial working clearance of the support shaft of the tipping bucket assembly; an excessively large or small clearance will affect its normal operation.
