	Wi-Fi Temperature Sensor The OEM Wi-Fi temperature sensor uses a thermistor to accurately measure temperatures. Perfect for slower changing temperatures and critical applications such as facilities or rooms. They can also be used for building applications such as controlling mold, mildew or dust mites. An integrated 802.11 b/g radio transmitter allows the device to be easily programmed to work with any existing Wi-Fi network. OEM Wi-Fi sensors can be easily programmed with Wi-Fi network security via a low cost USB programming cable, available here, and the free Wi-Fi Setup Utility for Windows® PC's, keeping the user's Wi-Fi network secure. User defined transmission intervals (heartbeats) and sensor threshold settings ensure that sensor data is received when needed, based on the application. All sensor data is securely transmitted through the Wi-Fi network to the iMonnit Online Sensor Monitoring software where it is stored and viewable from any web enabled device. The iMonnit online software system is completely white label (private brand) capable, allowing you to offer the online monitoring service as your own. Email and SMS text messages can be configured through the online system to alert users immediately when a defined parameter has been met or exceeded. « Learn more about OEM online monitoring software The Wi-Fi Setup Utility is currently only available for Windows® PC's. Mac support coming soon!
