ESP32 With Arduino IDE

Christmas 2015 yours truly was one of the lucky few in the world to receive the ESP32 for experimenting. The board was not assembled, and it was quite intimidating to assemble the board with just a fine tip solder. The experiment is documented at this URL: https://www.instructables.com/id/Beginners-ESP32-Gu... This afternoon, yours truly came across the Arduino Core for ESP32 on github URL here: https://git ...

Thermostats Finder ensure a thermal comfort to your devices

Thermal comfort is, when a temperature in a house is 21-24 °C and a relative humidity is .... No, sorry, your device can withstand much more. At least 0 to 60°C or much more. If you have a device, where you need to guide the temperature, then DIN-rail thermostats are the simplest usable solution. Series 7T from company Finder offers a possibility to use such thermostats to control heating, cooling (fans) or ...

Protecting wearable healthcare devices from static charges

Wearable technologies that incorporate physiological sensors are appearing on the market in so-called smart watches. Next generation monitoring devices will be worn on the body to monitor conditions such as blood glucose levels in near-real time and allow them to collect considerably more data over the course of a day. Initial examples of this novel approach such as wristbands that are capable of measuring ...
