 The Series WTDL Wireless Temperature/Humidity Data Logger is perfect for applications which require real-time monitoring or areas that are not as accessible to periodically retrieve the data. The data loggers can transmit up to 500 feet indoors and up to 2000 feet outdoors. The distance can be increased by using additional receivers. Wireless data is transmitted on a 2.4 GHz frequency allowing it to be used anywhere in the world. A network of data loggers can be separated into a smaller subnet. These subnets can all be controlled by a single PC. The Series WTDL data loggers also feature a user-programmable alarm. This alarm can be configured to show an on screen alarm, send a text message (standard SMS rates apply), or an email if an alarm condition is met.
