Sensor handles loss of power.

US company Measurement Computing has announced the WiFi-501-TP temperature data logging sensor.

Available in the UK from Adept Scientific, this is a wifi-based sensor with thermistor probe which measures the temperature and humidity of the environment in which the probe is situated. Data is transmitted wirelessly to a PC and is viewed using the software included. It can then be placed anywhere within range of the network.

If the sensor temporarily loses connectivity with the network, it will log readings until it is able to communicate again with the PC application, with a maximum of120 days at 10 second sample intervals. Measurement range is -40 to +125[degrees]C and the device is 802.11b compliant.


The device is battery-powered and, when configured using typical sampling periods such as once a minute it will operate for over a year. The battery can be recharged via a PC or USB +5 V wall adapter. The software will allow set-up, data logging and data review.
