In this example we take a look at the KY-017 Mercury Tilt Switch Module and connect this to a Raspberry Pi. This info is from wikipedia Mercury switches have one or more sets of electrical contacts in a sealed glass envelope that contains a small …

In this example we take a look at the KY-002 Vibration switch module and connect this to a Raspberry Pi. When the switch detects movement, the output of the module is sent low. The module is based around the Gaoxin SW-18010P vibration switch, lets look …

In this example we take a look at the KY-009 3-color full-color LED SMD module and connect this to a Raspberry Pi. RGB LEDs consist of one red, one green, and one blue LED. By independently adjusting each of the three, RGB LEDs are capable …

In this example we take a look at the KY-018 Photo resistor module and connect this to a Raspberry Pi using an ADC add on board A photoresistor (or light-dependent resistor, LDR, or photo-conductive cell) is a light-controlled variable resistor. The resistance of a photoresistor …

In this article we will connect a PIR to a raspberry Pi and light an LED if motion detected, in real life you would use a buzzer or sounder. Lets look at a PIR A passive infrared sensor (PIR sensor) is an electronic sensor that …

In this article we look at the TMP102 digital sensor and we will connect it up to a Raspberry Pi The TMP102 device is a digital temperature sensor ideal for NTC/PTC thermistor replacement where high accuracy is required. The device offers an accuracy of ±0.5°C …

The DS1624 consists of two separate functional units: a 256-byte nonvolatile E2 memory and a direct-to-digital temperature sensor. The nonvolatile memory is made up of 256 bytes of E2 memory. This memory can be used to store any type of information the user wishes. These …

In this example we look at the MMA7660FC accelerometer connected to a Raspberry pi The MMA7660FC is a digital output I²C, very low-power, low-profile capacitive micro-machined accelerometer featuring a low pass filter, compensation for zero-g offset and gain errors and conversion to six-bit digital values at …

In this example we will connect a MMA8452Q accelerometer  to a Raspberry Pi Lets look at some information about the sensor The MMA8452Q is a smart, low-power, three-axis, capacitive, micromachined accelerometer with 12 bits of resolution. This accelerometer is packed with embedded functions with flexible user programmable …

Raspberry Pi and MCP3424 A/D converter example, lets look at the device. The MCP3424 is a four channel low-noise, high accuracy delta-sigma A/D converter with differential inputs and up to 18 bits of resolution. The on-board precision 2.048V reference voltage enables an input range of …
