Keep the Manhole Secured with the New NBIoT Manhole Sensor

WoMaster released a new NBIoT manhole detection sensor that can be installed on the bottom of different manholes with high protection IP67 enclosure. It is designed with an ARM32 bit low power CPU with position detection and ultrasonic liquid sensor. It is powered by an 8000mAh Lithium battery which can last for 3 years under 4 times uplink per day. The Manhole sensor can send the real-time status of the manhole such as manhole tilt angle and water level to cloud server like ThingsMaster OTA through NBIoT B1/3/5/8/20/28 band to alarm illegal intrusion, dumping, or flood. The manhole sensor can be applied to many smart city projects to enhance public safety.
