LDO regulator boasts high PSRR
https://www.electronics-lab.com/ldo-regulator-boasts-high-psrr/
by Susan Nordyk @ edn.com: In addition to low noise, the LT3045 linear regulator from Linear Technology provides a PSRR (power supply rejection ratio) of >90 dB to 10 kHz and >70 dB to 2.5 MHz, quieting noisy or high-ripple input supplies. The LDO regulator’s ultralow spot noise of only 2 nV/√Hz at 10 kHz […]
Using Resistance Temperature Detector (RTD) With Arduino
https://www.electronics-lab.com/using-resistance-temperature-detector-rtd-arduino/
Most of hardware developers have used a temperature sensor in one or more of theirs projects. There are many types of temperature sensors, such as LM35, thermistors, and resistance thermometers. These types differ in response speed, temperature ranges, accuracy, and other factors. Resistance thermometer, which also known as Resistance Temperature Detector (RTD), is a device […]

E-paper Shield Kit for the Teensy
https://www.electronics-lab.com/e-paper-shield-kit-teensy/
Jarek tipped us with his latest project, an E-paper screen shield kit for Teensy. He writes: E-paper screens have been hacked out of Kindles and store price tags for a while, but this is the first ( to my knowledge ) open-source project which offers a simple and cheap interface for E-paper. After you prototype […]
Clinical-grade human body temperature sensor has ±0.1°C accuracy

Maxim Integrated has posted details of the MAX30205 temperature sensor for thermometer applications. The sensor accurately measures temperature and provide an overtemperature alarm/interrupt/shutdown output. by Graham Prophet @ edn.com The chip converts the temperature measurements to digital form using a high-resolution, sigma-delta, ADC. Accuracy meets clinical thermometry specification of the ASTM E1112 when soldered on […]

ray @ rayshobby.net build a wifi enabled color led matrix using ESP8266. He writes: Last Thursday I had a lot of fun doing a workshop at my college (UMass Amherst) where I taught students to use a WiFi-enabled Color LED matrix combined with Javascript programs to create animations displayed onto the LED matrix. The matrix […]
4-20 mA current output for Arduino Uno
https://www.electronics-lab.com/4-20-ma-current-output-arduino-uno/
Giovanni Carrera writes: The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller ATmega328 and numerous other chips, such as the PIC. One of the more interesting applications of this circuit would be to replace or to realize a smart sensor with Arduino.” 4-20 mA […]
