HEDGEHOG GESTURE SENSOR BUILT WITH CHEAP TIME OF FLIGHT MODULES

HEDGEHOG GESTURE SENSOR BUILT WITH CHEAP TIME-OF-FLIGHT MODULES

Arduino News / By

Time-of-flight sensors used to be expensive obscurities, capable of measuring the travel time of photons themselves and often used for tracking purposes. However, the technology is cheaper now, such that [jean.perardel] has used TOF sensors to build a useful and affordable gesture-tracking system. The system relies on four VL53L1X time of flight sensors, which have a […]

MONITORING WATER QUALITY USING LOTS OF SENSORS AND MACHINE LEARNING

MONITORING WATER QUALITY USING LOTS OF SENSORS AND MACHINE LEARNING

Arduino News / By

Despite great progress over the past century, more than a billion people still don’t have access to clean drinking water today. Much of the water on Earth’s surface is polluted, but it’s not always easy to tell a dirty stream from a clean one. Professional kit for water analysis can be expensive, which is why

HSM 20G temperature humidity analog sensor Nokia5110 LCD

HSM-20G temperature & humidity analog sensor + Nokia5110 LCD

LED Projects, Phone Projects / By

Temperature and humidity measurement are always a nice addition to hobbyist projects. In my previous post, I’ve discussed the DHT11 sensor, which is capable of measuring both temperature and humidity. They are digital sensor and provide calibrated outputs with temperature and relative humidity. I’ve also demonstrated how to interface with Arduino and display it on

MEASURING ELECTROMAGNETIC FIELDS WITH JUST AN ARDUINO AND A PIECE OF WIRE

MEASURING ELECTROMAGNETIC FIELDS WITH JUST AN ARDUINO AND A PIECE OF WIRE

Arduino News / By

Electromagnetic interference problems can be a real headache to debug. If you need to prove what causes your WiFi to slow down or your digital TV signal to drop, then the ability to measure electromagnetic fields (EMF) can be a big help. Professional equipment is often very expensive, but building an EMF detector yourself is
