IOTA MHC Manhole Cover Sensor R4

Some manholes need instant monitoring: to reduce risk of accidents or to detect intruders or simply to get immediate alert when a manhole cover is being opened, to trigger an appropriate action. This is what IOTA MHC has been designed for.It is a robust, industrial grade device, with protection rating IP69. It is very difficult to be tampered, so one can be sure to be alerted whenever a manhole cover is opened or someone is just playing with the device to stop it from alerting you. And, what is more, it is mobile and installable in seconds.
