In this example we will connect a CCS811 gas sensor to an arduino, lets look at the sensor CCS811 is a low-power digital gas sensor solution, which integrates a gas sensor solution for detecting low levels of VOCs typically found …

In this article we look at the CC3000 WiFi shield. We will use the aRest example for CC3000, and we will then use a web address to manipulate some LED’s on and off. Lets look at the CC3000 chip The …

The MLX90615 is a miniature infrared thermometer for non-contact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same miniature TO-46 can. The infrared thermometer comes factory calibrated with a digital …

The VL53L0X is a new generation Time-of-Flight (ToF) laser-ranging module housed in the smallest package on the market today, providing accurate distance measurement whatever the target reflectances unlike conventional technologies. It can measure absolute distances up to 2m, setting a …

In this example we will connect a SHT20 temperature sensor to an Arduino Uno. Lets look at some information about the sensor The SHT20 humidity and temperature sensor of Sensirion has become an industry standard in terms of form factor …

In a previous example we used Neopixel libraries and had a couple of code examples. Now we look at a couple of different libraries, the example built in scrolls text on the screen AliExpress.com Product – WS2812 LED 5050 RGB …

I like the WS2812 Neopixel boards, modules and LEDs you can buy and have been looking at some of the variants but coming at over $35 for some of these I baulked at buying them, recently I found compatible boards …

In this example we look at an VEML6070 UV sensor and connect it to an Arduino UNO VEML6070 is an advanced ultraviolet (UV) light sensor with I2C protocol interface and designed by the CMOS process. It is easily operated via …

The MPL3115A2 is a compact, piezoresistive, absolute pressure sensor with an I2C digital interface. MPL3115A2 has a wide operating range of 20 kPa to 110 kPa, a range that covers all surface elevations on earth. The MEMS is temperature compensated …

In this example we look at a module based on the TCRT5000 Reflective Optical Sensor with Transistor Output. A very basic description of the TCRT500 is that it is an Infrared LED and an Infrared detector. It works by transmitting …

The QRE1113 features an easy-to-use analog output, which will vary depending on the amount of IR light reflected back to the sensor. The QRE1113 IR reflectance sensor is comprised of two parts – an IR emitting LED and an IR …

The next module to take a look at is quite often entitled 4-CHANNEL LINE TRACKER SENSOR, thats exactly what it does the module consists of a main module and 4 little sensor/reciever modules that connect via a 3 pin cable …
