Grove Temperature Sensor v1.2 is perfect for you. It uses a thermistor as a form of resistance value to alter the Vcc. The resistance of a thermistor will increase when the ambient temperature decreases. Its this characteristic that we use to calculate the ambient temperature. Depending on the temperature measured, it supplies an analog signal from 0 to 5 Vcc. The detectable range of this sensor is -40 to 125C and the accuracy is 1.5C.

This IR thermal camera carries a 1612 array of thermal sensors (MLX90641) and it can detect the temperature of objects from far away with a center area accuracy of 1 and average accuracy of 1.5. In order to obtain the thermal images easily, the I2C protocol is used to get the low-resolution images from the camera. The FOV (Field of View) of this camera is 110x75, and the temperature measurement range is -40 to 300.

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 is a convenient plug-and-play system with a specialized interface, but it doesn't mean that you cannot use it in an open ecosystem like a breadboard. With this special designed cables, you can easily integrate the comprehensive Grove system with breadboard or other microcontrollers that don't have compatible Grove Base Shield for now. If you are tinkering around Raspberry Pi, Arduino, Cubieboard or Beagle Bone and be fond of the advantage of Grove, you should use this cable.

The Universal 4 Pin Buckled Cable is made for the Grove System to connect all of the Twigs to the Stem – Basic Shield

The Grove – UV Sensor is used for detecting the intensity of incident ultraviolet(UV) radiation. This form of electromagnetic radiation has shorter wavelengths than visible radiation. It is based on sensor GUVA-S12SD. It has a wide spectral range of 200nm-400nm. The module will output an electrical signal which is varied with the change of the UV intensity. UV sensors are used for determining exposure to ultraviolet radiation in the laboratory or environmental settings.
