This device is based on SI1145, a new sensor from SiLabs. The Si1145 is a low-power, reflectance-based, infrared proximity, UV index and ambient light sensor with I2C digital interface and programmable-event interrupt output. This device offers excellent performance under a wide dynamic range and a variety of light sources including direct sunlight.

The Grove Switch (P) is a mini Single Pole, Double Throw (SPDT) slide switching device. But, what does P mean? P stands for Panel mount. With panel mount feature, you can use it as you wish, for example, you can attach the switch to a cut out in a panel, a box, or a frame. This switch is great for ON/OFF situations on many of our boards; moreover, It is a long-lasting and reliable device of great build quality.

Grove – DHT22 is a high accuracy temperature and humidity sensor based on the DHT22 module (also known as AM2302 or RHT03). High-cost performance and high precision make it ideal for temperature and humidity monitoring of Arduino and Raspberry Pi, you can also use it to make a thermometer and hygrometer.

The IR thermal camera carries a 32×24 array of thermal sensors (MLX90640), it can detect the temperature of objects from feet away with the accuracy of ±1.5℃. In order to obtain the thermal image easily, the I2C protocol is used to get the low-resolution image from the camera. The FOV(Field of View) of this camera is 55°x35°, and the temperature measurement range is -40℃~300℃.

The joystick has a specialty of two direction movements. The two direction movements will output different analog signals as they are actually two potentiometers. The X and Y axes are two ~10k potentiometers which control 2D movement by generating analog signals. When the module is in working mode, it will output two analog values, representing two directions. its output values are restricted to a smaller range (i.e. 200~800), only when being pressed that the X value will be set to 1023 and the MCU can detect the action of pressing.

Grove Tilt Switch v1.1, which you can tilt and operate easily. It is an equivalent of a button and is ready to use with a micro-controller as a digital input.
