The Sense IoT wireless AC voltage detection sensor can interface with other devices to detect voltage from 4 VAC to 500 VAC. The sensor reports presence or absence of voltage when the 4 volt threshold is breached. It is intended for use on power sources or power supplies up to 500 VAC. Not intended for voltages higher than 600 VAC. Perfect for monitoring electrical appliances. • Wireless interface for detecting voltage • Detects voltage from 4 to 500 VAC The Sense IoT wireless AC voltage detection sensor can be connected to the hot and neutral terminals of an electrical device or power supply line, triggering on the state change from voltage presence to absence and vice versa. The information is sent to the Sense IoT Online Sensor Monitoring and Notification System, where the data is displayed as either “No Voltage” or “Voltage Detected”. The data is stored in the online system and can be reviewed and exported as a spread sheet or graph. Notifications can also be set up through the online system to alert the user when certain criteria have been met.
