How to Set Up the DHT11 Humidity Sensor on an Arduino
https://www.electronics-lab.com/how-to-set-up-the-dht11-humidity-sensor-on-an-arduino/
by circuitbasics.com: Because of their low cost and small size, DHT11 humidity and temperature sensors are perfect for lots of different DIY electronics projects. Some projects where the DHT11 would be useful include remote weather stations, home environment control systems, and agricultural/garden monitoring systems. The DHT11 is a digital sensor that lets you easily get relative […]
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 […]
Get rid of unpleasant odors easily and effectively
https://www.electronics-lab.com/get-rid-of-unpleasant-odors-easily-and-effectively/
USM-MEMS-VOC module evaluates rate of air pollution by contaminants such as cigarette smoke and cooking odors and allows control of air ventilation system on demand. Modul USM-MEMS-VOC is based on the innovative and highly stable TGS 8100 MEMS semiconductor sensor TGS8100 from Figaro. In the presence of detectable gas, sensor resistance decreases depending on gas […]
Temperature controlled coolbox
https://www.electronics-lab.com/temperature-controlled-coolbox/
by nusnel @ instructables.com: For my monthly maker column in Dutch newspaper “De Volkskrant”, I made a coolbox in which you can control the temperature in three separate compartments to keep craft beer at just the right temperature. The contraption I build uses three Peltier-elements to cool, an old desktop computers power source, an LCD to […]

Jeremy Morgan @ jeremymorgan.com writes: Today I’m going to show you how to make sort of a mini weather station with a Raspberry Pi. This is an ongoing project of mine that I’ve been tinkering with so I’ll share my learnings with you. It started with a project I wrote about last month, and is […]
Freeze 75 – and you have a temperature under control
https://www.electronics-lab.com/freeze-75-and-you-have-a-temperature-under-control/
Freeze 75 spray will enable you to find faulty component or also to protect components from overheating during soldering. A device operates OK until it reaches stable operating temperature … a typical situation in praxis usually caused by a faulty component or faulty (cold) joint. Localization of such a fault is easy only if we […]
A Spark.io Indoor Ambient Quality Monitor
https://www.electronics-lab.com/a-spark-io-indoor-ambient-quality-monitor/
Davide Gironi has build an indoor ambient quality monitor based on particle.io : SXAM (Spark to Xively AMbient quality monitor), is an ambient quality monitor that logs 4 environmental parameters to the xively.com and display the ambient status by using for RGB leds. SXAM logs: Humidity, Temperature, Ambient noise, Brightness, Note: Spark.io is now Particle.io. […]
A Xively AMbient QUality MOnitor built on ATmega328
https://www.electronics-lab.com/a-xively-ambient-quality-monitor-built-on-atmega328/
Davide Gironi has build an indoor ambient quality monitor that is able to measure temperature, humidity, noise and brightness and indicate the ambient quality using 4 bi-color LEDs. He writes: The data it is logged to the xively.com platform, and displayed to the user through 4 bi-color leds. It can be used to monitor you […]
DIY Weather Station with Bluetooth
https://www.electronics-lab.com/diy-weather-station-with-bluetooth/
by Matej Blagšič @ instructables.com: Recently I attended a course in our University of Electrical Engineering and we were making ourselves a small weather station. It included learning about soldering, sensors and arduino. It was super fun making it with little kids and other high school kids my age. I will show you how you can […]
