<p>A remote sensing system and method for instrumenting the entries to manhole enclosures, in order to provide a platform and means f sensing environmental parameters within and around the enclosures and wirelessly transmitting those parameters to a distant site. T system comprises a housing (10) with sensor for monitoring environmental prararreter in the vicinity of the manhole. A microcontrol (12) in the housing sends the parameters to a radio module (13), which transmits the parameters to a communication device for alerting a user that a manhole has been tampered with.</p>
