Low-Power Rainfall Recorder



As the name suggests, the low-power rainfall recorder is an instrument designed for low-power monitoring and recording of rainfall. It automatically observes and stores parameters related to "rainfall." Composed of a rainfall sensor, data acquisition recorder, built-in battery, and other components, it features low power consumption, high sensitivity, easy installation, simple operation, and user-friendly functionality. It can be used for long-term observation and recording of rainfall data in the field, with data periodically retrieved using a (notebook) computer. Data is stored locally and does not require a communication network; it is powered by a built-in battery and does not need an external power supply.

Suitable for applications in agriculture, industrial automation engineering, smart building systems, workshops, warehouses, museums, laboratories, greenhouses, and other settings. It can provide data for measuring precipitation, rainfall intensity, precipitation duration, and rainfall monitoring for meteorological stations, hydrological stations, agriculture, forestry, and field observation stations. It also supplies rainfall data for flood control, water supply scheduling, power stations, and reservoir water management.

Technical Parameters:

◇ Measurement Range: Rainfall intensity 0–4 mm/min

◇ Measurement Accuracy: ±0.2 mm

◇ Resolution: 0.2 mm

◇ Measurement Error: ±2%

◇ Storage Capacity: 16 MB (can store data continuously for 10 years)

◇ Data Export: USB interface for convenient data extraction

◇ Catchment Diameter: φ200 mm

◇ Material: ABS

◇ Power Supply: Built-in lithium battery (theoretical lifespan of 3 to 5 years)

◇ Lithium Battery Parameters: 3.0 V, 4 Ah

◇ Operating Temperature: -40°C to 70°C (non-freezing conditions)

◇ Compatible Product: 2.3-meter stainless steel bracket (sold separately)

Features:

◇ Low overall power consumption; no power usage when there is no rainfall. Powered by a built-in lithium battery, it can operate continuously for 3 to 5 years with no maintenance required;

◇ Equipped with upper computer software, which allows setting the data acquisition interval and automatically summarizing and calculating rainfall per minute, hour, day, month, and year;

◇ Suitable for long-term field use, does not require a communication network for data transmission, and does not need an external power supply;

◇ Built-in filtering circuit uses resistance-capacitance to eliminate spike interference, effectively resolving the issue of multiple rainfall signals being output from a single tip;

◇ Compact size, simple operation; recording interval can be set from 1 minute to 24 hours as required;

◇ Made of ABS engineering plastic, rust-free with excellent appearance quality;

◇ The rain collector is injection-molded from ABS engineering plastic with a smooth surface, minimizing errors caused by water retention;

◇ The tipping bucket component support system is precision-manufactured with low frictional torque, ensuring smooth tipping bucket operation;

◇ The base is equipped with a leveling bubble to assist in adjusting the device to the proper level using the feet;

◇ The software allows convenient data viewing, and data from the recorder can be periodically exported to a computer and saved as an Excel spreadsheet file for further analysis with other data processing software.
