In this example we take a look at the KY-011 Two color LED module and connect this to a Raspberry Pi. As you may have guessed this is a common cathode LED with a red anode and a green anode. You can adjust the amount …

In this example we take a look at the KY-003 Hall Magnetic Sensor Module and connect this to a Raspberry Pi. The KY-003 consists of a 3144EUA-S sensitive Hall-effect switch These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended …

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 …
