  • Replacement Weather Station Rain Gauge - Tipping Bucket Type 0.3mm Rain / pulse ()

    his tipping bucket rain gauge has a magnetic reed switch that closes momentarily each time the gauge measures 0.011" (0.2794 mm) of rain.

    The 9 foot (3 meter) cable terminates in an RJ11 modular plug, and can easily be extended using a common telephone extension cable.

    The gauge can be easily connected to an Arduino, Rapberry Pi, or any microcontroller. Commonly a pull-up resistor (4.7k ohms is typical) will be used to pull the input pin high, and the other side of the gauge's switch will be connected to ground, pulling the pin low each time the switch closes.

  • Ultrasonic Distance Sensor ()

    ultrasonic sensor provides an easy method of distance measurement. This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects.

    Interfacing to a microcontroller is a snap. A single I/O pin is used to trigger an ultrasonic burst (well above human hearing) and then "listen" for the echo return pulse. The sensor measures the time required for the echo return, and returns this value to the microcontroller as a variable-width pulse via the same I/O pin.

    Application Ideas:

    • Security systems
    • Interactive animated exhibits
    • Parking assistant systems
    • Robotic navigation

  • I2C/SPI BMP280 3.3 Digital Barometric Pressure Altitude Sensor Module High Precision Atmospheric Module for Arduino ()
    • Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI!
    • This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy

  • VL53L0X Time-of-Flight (ToF) Laser Ranging Sensor Breakout 940nm GY-VL53L0XV2 Laser Distance Module I2C IIC 3.3V/5V ()
    The VL53L0X from ST Microelectronics is a time-of-flight ranging system integrated into a compact module. This board is a carrier for the VL53L0X, so we recommend careful reading of the VL53L0X datasheet (1MB pdf) before using this product. 

    The VL53L0 uses ST's FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to reach the nearest object and be reflected back to a detector, so it can be considered a tiny, self-contained lidar system. This time-of-flight (TOF) measurement enables it to accurately determine the absolute distance to a target without the object's reflectance greatly influencing the measurement. The sensor can report distances of up to 2 m (6.6 ft) with 1 mm resolution, but its effective range and accuracy (noise) depend heavily on ambient conditions and target characteristics like reflectance and size, as well as the sensor configuration. (The sensor's accuracy is specified to range from ±3% at best to over ±10% in less optimal conditions.) 

    Ranging measurements are available through the sensor's I⊃2;C (TWI) interface, which is also used to configure sensor settings, and the sensor provides two additional pins: a shutdown input and an interrupt output. 

    The VL53L0X is a great IC, but its small, leadless, LGA package makes it difficult for the typical student or hobbyist to use. It also operates at a recommended voltage of 2.8 V, which can make interfacing difficult for microcontrollers operating at 3.3 V or 5 V. Our breakout board addresses these issues, making it easier to get started using the sensor, while keeping the overall size as small as possible.
