Raspberry PI

In this article we look at a fairly new piece of kit the Raspberry Pi 400 The Raspberry Pi 400 is a complete Raspberry Pi 4-based personal computer which is…

In this article we look at 10 sensors and modules that you can use with an Arduino and various other micro controllers and development boards like the ESP32, ESP8266 and the Raspberry Pi that cost under $2

The TCS3472 device provides a digital return of red, green, blue (RGB), and clear light sensing values. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately.

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 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 temperature sensing applications.

Here we look at 3 various Raspberry PI apps on android devices These seem to be a a better standard than the Arduino ones we looked at previously RPiRef on…
