Rain Sensor Module Water Droplet Detector

The SparkFun weather meter kit is a set of basic mechanical components for building a weather station. This kit represents the three basic elements of weather measurement: wind speed, wind direction and precipitation. Whether you are a farmer, a professional meteorologist or a weather enthusiast, building your own weather station can be a truly rewarding project. However, when it comes to measuring the weather, you need some pretty specialised sensors.

The SparkFun micro:Climate kit is a complete weather station kit that builds on the weather:bit carrier board with weather and soil moisture sensors, all powered by the micro:bit. board.

The SparkFun Weather Meter Kit is a set of basic mechanical and electronic components to build a weather station. With the SparkFun Arduino IoT Weather Station kit in sight, you can create your own weather station. The kit allows monitoring via the Arduino Cloud, an IoT platform.

The BME280 is an environmental sensor (SEN0236) integrating a temperature sensor, a humidity sensor and a barometer. Powered from 3.3 V to 5 V with I2C and SPI interface. Measuring range: temperature: -40 °C to 85 °C, humidity: 0 %RH to 100 %RH, pressure: 300 hPa to 1100 hPa.

This module includes the BMP280 component that converts atmospheric pressure, temperature and humidity with high precision into a digital signal.
The equipment uses the two I2C and SPI interfaces. The very good measurements made by the BMP280 allows the module to be used as an altimeter.
Its 5-pin straight connector allows easy connection to other electronic boards. BMP280 Temperature Barometric Pressure Sensor Module/SPI features:
- Interfaces:
       -I2C (up to 3.4 MHz)
       -SPI (up to 10 MHz)
- Supply voltage: 1.8-5VDC
- Module operating range:
       - Temperature: -40ºC to + 85ºC
0-100%
       - Pressure: 300-1100 hPa
- Resolution of the measures:
       - Temperature: 0.01ºC

This module includes the component BME280 that is translated into a digital signal.
The equipment uses the two I2C and SPI interfaces. The BME280 does not allow the module to be used as an altimeter as opposed to its successor BMP280.
