Abstract
An apparatus for monitoring a pit lid of a pit, including a magnetic sensor for measuring the strength of a magnetic field, wherein when the apparatus is installed on the pit lid, the measured magnetic strength indicates whether the apparatus is in proximity to a magnet disposed in the pit. The apparatus is configured to determine, based at least partially on the magnetic strength measured by the magnetic sensor, a status of the pit lid, the status indicating whether the pit lid is closed.
Claims18
An apparatus for monitoring a pit lid of a pit, including:
- a magnetic sensor for measuring a strength of a magnetic field, wherein when the apparatus is installed on the pit lid, the measured magnetic field strength indicates whether the apparatus is in proximity to a magnet disposed in the pit;
- and
- a motion sensor for continuously monitoring the pit lid to detect movements of the pit lid;
- wherein the apparatus is configured to determine, based at least partially on the magnetic strength measured by the magnetic sensor, a status of the pit lid, the status indicating whether the pit lid is closed;
- and
- wherein the apparatus is configured to detect activity associated with the pit lid and increment a counter in the motion sensor without turning on a microcontroller of the apparatus.
A method for monitoring a pit lid of a pit, including:
- measuring, by using a magnetic sensor, a strength of a magnetic field in the vicinity of a monitoring apparatus installed on the pit lid, the measured magnetic field strength indicating whether the monitoring apparatus is in proximity to a magnet disposed in the pit;
- determining, based at least partially on the magnetic strength measured by the magnetic sensor, a status of the pit lid, the status indicating whether the pit lid is closed;
- and
- measuring, by using a motion sensor, movements of the pit lid for continuously monitoring movements of the pit lid;
- wherein the apparatus is configured to determine, based at least partially on the magnetic strength measured by the magnetic sensor, a status of the pit lid, the status indicating whether the pit lid is closed;
- and
- wherein the apparatus is configured to detect activity associated with the pit lid and increment a counter in the motion sensor without turning on a microcontroller of the apparatus.
