Relay Control With Raspberry Pi

Most of us have faced the problem when the raspberry pi board is not capable of switching between multiple devices simultaneously. So connecting multiple devices using the 26 GPIO pins is not possible. Moreover, it cannot be extended beyond 26 so more than 26 devices cannot be connected. This problem can be solved by using a GPIO header. On one header, we…

Acceleration Measurement Using BMA250 and Raspberry Pi

BMA250 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as a 16-bit two’s complement and is accessible through the I2C digital interface. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion…

Temperature Measurement Using TMP112 and Particle Photon

TMP112 High-Accuracy, Low-Power, Digital Temperature Sensor I2C MINI module. The TMP112 is ideal for extended temperature measurement. This device offers an accuracy of ±0.5°C without requiring calibration or external component signal conditioning. In this tutorial, the interfacing of the TMP112 sensor module with particle photon has been illustrated. To read the temperature values, we have…

Pressure and Temperature Monitoring Web Server Using ESP8266 and CPS120

The CPS120 is a high-quality, low-cost capacitive absolute pressure sensor solution with a compensated digital pressure and temperature output for low-pressure applications, such as barometric sensing. A robust sensor design (single crystal silicon structure and backside pressure port) makes the CPS120 suitable for extreme temperatures and harsh environments. Today we will be demonstrating how to monitor the data…

Humidity and Temperature Observer Using Raspberry Pi With SHT25 in Python

Being an enthusiast for Raspberry Pi, we thought of some more spectacular experiments with it. In this campaign, we will be making a Humidity and Temperature Observer that measures Relative Humidity and Temperature using Rasberry Pi and SHT25, Humidity and Temperature sensor. So let’s have a look at this journey to create a homemade Humidity and Temperature Observer…

Temperature Measurement Using MCP9803 and Particle Photon

MCP9803 is a high precision 2-wire temperature sensor. They are equipped with user-programmable registers which facilitate temperature sensing applications. This sensor is suitable for a very sophisticated multi-zone temperature monitoring system. This lesson shows the interaction of the MCP9803 sensor module with particle photon. To read temperature values, we use particle photon with an I2c…
