Abstract
A method of detecting water within a pit of an elevator shaft including: detecting water within a pit of an elevator shaft using a water sensor; wirelessly transmitting a notification to a controller; and transmitting the notification to a computing device.
Claims19
A method of detecting water within a pit of an elevator shaft, the method comprising:
- detecting water within a pit of an elevator shaft using a water sensor;
- wirelessly transmitting a notification to a controller;
- transmitting the notification to a computing device;
- wherein the water sensor is configured to send a periodic heartbeat signal to the controller in response to water not being detected within the pit;
- and
- wherein the periodic heartbeat signal comprises water detection status and battery voltage.
3 more elements
A water sensor for detecting water within a pit of an elevator shaft, the water sensor comprising:
- a power source configured to power the water sensor;
- a controller configured to control operation of the water sensor
- a sensing device configured to detect water;
- and
- a communication device configured to wirelessly transmit a notification to a controller of an elevator system associated with the elevator shaft in response to water being detected by the sensing device and to send a periodic heartbeat signal to the controller in response to water not being detected and wherein the periodic heartbeat signal comprises water detection status and battery voltage.
