Honeywell changes magnetic sensor design, forever

Honeywell Sensing and Control has designed a position sensor IC which combines the sensitivity of an anisotropic magnetoresistive (AMR) sensor with the low power operation of a Reed switch. The range of magnetoresistive sensor ICs is called Nanopower reflecting a typical power consumption of 360nA. This is a ten-fold reduction in power consumption on previous …

Solar Driveway Light to MSP430 Wireless Sensor Node

The basic idea of this project is to convert a $3-4 solar light found at Lowes and Home Depot hardware store (here in the US) into a wireless remote sensor node.  The node will utilize an MSP430G2553 MCU and a nRF24L01+(w/ spirilis library) wireless module to send light intensity (photoresitor that came with solar driveway …

A simple analog proximity sensor with digital interface (for Raspberry Pi) [last update: Feb 7, 2014]

Raspberry Pi has a Broadcom BCM2835 chip, which controls 26 GPIO (general purpose input/output) pins. There are C library or RPi.GPIO python package available online that can be used to control the pins. The RPi.GPIO package is by default included in most Raspberry Pi system, such as Raspbian, a RPi version of Debian linux system. One …

TSL2584TSV Ambient Light Sensor

The TSL2584TSV is a very-high sensitivity light-to-digital converter that transforms light intensity into a digital signal output with a fast-mode I²C interface. The device combines one broadband photodiode (visible plus infrared), one infrared-responding photodiode, and a photopic infrared-blocking filter on a single CMOS integrated circuit. Two integrating analog to Digital Converters (ADCs) convert the photodiode …
