The Si7021 I2C Humidity and Temperature Sensor is a monolithic CMOS IC integrating humidity and temperature sensor elements, an analog-to-digital converter, signal processing, calibration data, and an I2C Interface. The Si7021 offers an…
The LX1972 is a low cost silicon light sensor with spectral response that closely emulates the human eye. Patented circuitry produces peak spectral response at 520nm, with IR response less than ±5%, of the peak response, above 900nm. The photo…
In this example we will connect a GA1A12S202 Log-Scale Analog Light Sensor to a Chipkit Uno The features of this sensor are as follows Output voltage increases with light on the sensor Logarithmic response not only gives more sensitivity in…
TEMT6000 ambient light sensor is a silicon NPN epitaxial planar phototransistor in a miniature transparent 1206 package for surface mounting. It is sensitive to visible light much like the human eye and has peak sensitivity at 570 nm. Features •…
The ML8511 measures the amount of ultra violet rays contained in sunlight, and it is used for the equipment which displays the suntan by a ultra violet rays, the guidance for UV care of skin, etc The sensor detects 280-390nm…
The MLX90614 is a non-contact infrared thermometer with a measurement range from -70 to +380 degree Celsius. Just connect the four leads to your Wemos and you will have a accurate thermometer with a resolution of 0.01 and a accuracy of…
In this example we connect the MCP9808 to a Chipkit Uno The MCP9808 digital temperature sensor converts temperatures between -20°C and +100°C to a digital word with ±0.5°C (max.) accuracy. The MCP9808 comes with user-programmable registers that provide flexibility for…
SHT31 is the next generation of Sensirion’s temperature and humidity sensors. It builds on a new CMOSens® sensor chip that is at the heart of Sensirion’s new humidity and temperature platform. The SHT3x-DIS has increased intelligence, reliability and improved accuracy specifications…
These are interesting modules that you can buy from various online sources. They comprise of 2 4×7 7 Segment displays, 8 push buttons and 8 LEDs. The chip that performs all the magic is a TM1638. The module I bought…
I recently spotted a nice little compact development board for the PIC12F675, since this was a PIC that I hadn’t looked at I decided to buy one. This is the board I bought About the board External reset button. Two…
