The EL-WiFi data logging sensors wirelessly stream environmental data at regular intervals to a host PC. Position sensor using built-in Wi-Fi range detection indicator; once set up within range of a Wi-Fi router, the sensor stays where you want it and you can monitor the data from your PC. The EL-WiFi sensors are 802.11b compliant and support security protocols WEP, WPA/WPA2-PSK—unlike many other wireless data loggers, these sensors communicate through any Wi-Fi router available worldwide. Use the LCD to read data locally, including min/max readings, Wi-Fi connection and signal strength. Data loggers are IP55-rated and include rechargeable batteries.
