Compatible with micro:bit, Arduino, ESP32, and Raspberry Pi
Ideal for weather stations, environmental monitoring stations, and smart farms
Operates at a working voltage of 3 to 5.5V DC
The DFRobot Gravity: Tipping Bucket Rainfall Sensor - I2C & UART is a reliable and sophisticated instrument designed for accurate measurement of rainfall. This device operates on the principle of tipping bucket rainfall, offering users the ability to measure rainfall in millimeters and monitor system operating time.
The sensor is designed with a hollow bottom, a feature that allows for automatic drainage of rainwater. This design enhances the stability and sensitivity of the device. The sensor supports I2C and UART data outputs, ensuring compatibility with a range of devices including micro:bit, Arduino, ESP32, and Raspberry Pi.
The Tipping Bucket Rainfall Sensor is integrated with the user-friendly Gravity interface and comes with ready-to-use libraries. This makes it an ideal choice for setting up a rain monitoring system. The sensor is capable of providing high-quality rainfall data, making it suitable for use in weather stations, environmental monitoring stations, and smart farms.
The tipping bucket rainfall sensor is a widely used device in meteorological observations. It comprises a collection container and a measuring mechanism. During rainfall, water enters the collection container via the top inlet and flows into the tipping bucket through a funnel. When a certain volume of water accumulates, the tipping bucket tips over, generating a pulse signal with each tip. The number of pulse signals is recorded, enabling the controller to calculate the amount of rainfall.
The sensor operates at a working voltage of 3 to 5.5 V DC and a working current of less than 3 mA. It has a resolution of 0.28 mm and can function in temperatures ranging from -40 to 85 °C.

The RA number is valid for 30 days. The returned item must be received within that period.
The RA number must be included with the return.
Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
Clearance Items — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
While the same return policy applies, these orders require a separate contact process for returns.
RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets.
Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
