Free Energy to Charge Devices

Intel is researching technology to harvest free energy from the environment, which could lead to devices such as mobile phones running for indefinite periods without recharging. The company said it was working on tiny sensors that could capture energy from sources such as sunlight and body heat. In the future, such energy could be used to power personal electronic devices such as cell phones. Recharging themselves by scavenging free energy allows the sensors to continuously record and transmit readings over wireless networks, without any human involvement. Read more.

WS501 series All in one weather station with integrated Kipp and Zonen Pyranometer

WS501 series Compact Weather Stations for measuring of air temperature, relative humidity, solar radiation, air pressure, wind direction and wind speed. Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature. The world renowned technology of Kipp+Zonen CMP3 is integrated. Ultrasonic sensor technology is used to take wind measurements. Measurement output can be accessed by the following protocolls: UMB-Binary, UMB-ASCII, SDI-12, MODBUS. One external temperature or rain sensor is connectable. The WS503 is a similar sensor available with a tiltable pyranometer for plane of array measurements of solar panels efficiency. Surface temperature and rainfall accessory sensors are also available as add on to the weather station.
