SRF01 Sensor teardown and reverse engineering


https://www.electronics-lab.com/srf01-sensor-teardown-and-reverse-engineering/

Jaanus Kalde wanted to know why his SRF01 sensor fails after dropping from the air so he did a reverse engineering on it. I needed small ultrasonic sensors for a flying sensor. So I got the smallest one – SRF01. Quite nice unit, works down to 0 cm. There were some problems with it – Maximum […]

Sensor Technology for Health and Fitness Applications


https://www.electronics-lab.com/sensor-technology-for-health-and-fitness-applications/

By Jon Gabay @ digikey.com: Determining the state of our health has always been a matter of finding a way to monitor and measure the body’s most basic functions. Before instrumentation, visual indicators were used that allowed us to know, for example, what our body temperature should be, what a healthy pulse is, and what an […]

by wb8nbs.wordpress.com: This project was done for a Friend Of a Friend. He needs to monitor water flow rate and quantity for his solar heating projects. He is mainly interested in this two inch sensor but also sent along a small plastic hose bib type similar to the Adafruit 828. Both of these sensors are turbine […]

Adding Sensors to Monitor Hive Health


https://www.electronics-lab.com/adding-sensors-to-monitor-hive-health/

by Nathan Seidle @ makezine.com: The Digital Beehive uses Wi-Fi to broadcast a beehive’s weight, humidity, temperature, and battery voltage every minute to SparkFun’s data channel service called Phant. The raw data can be seen here but you can view some prettier graphs of the data here on analog.io (sign-in required). Adding Sensors to Monitor Hive […]

Humidity sensor using 8051


https://www.electronics-lab.com/humidity-sensor-using-8051/

by circuitstoday.com: This project is about a simple humidity sensor based on 8051 microcontroller. Humidity sensor is also called hygrometer. This circuit can sense relative humidity (RH) from 20% to 95% at an accuracy of 5%. The humidity information is displayed on a 16×2 LCD display. A relay is also provided which is set to be […]
