We would like to introduce the features of the new 3D ToF sensor “TPHT4040”, which was announced in an official press release on November 20, 2012.
Deep Power Down Mode
Our new 3D Time-of-Flight (ToF) sensor incorporates a low-power sleep state mode called “Deep Power Down Mode” that is significantly reduce energy consumption . This mode enables the sensor to operate on an event-driven basis, activating or resuming operation only when movement is detected within a predefined range. When no significant changes in sensor output are observed for a specified period, the sensor seamlessly transitions into a deep sleep state. This process minimizes power usage during inactivity, making it ideal for applications requiring battery-friendly operation.
Key benefits of the “Deep Power Down Mode”
Commercial facilities:
Sensors remain in a low-power state during periods of minimal nighttime access and activate only when movement is detected.
Factories:
During non-operational hours, sensors monitor the environment efficiently by activating only when people are present.
Demonstration (YouTube)
(1) When a person is 2m or more away from the sensor, the sensor seamlessly transitions into a deep sleep state, reducing power consumption.
(2) When a person comes up to 1m, the sensor to activate or resume operation in response to detecting movement.
(3) When the person moves away to 2m again, the sensor returns to a deep sleep state.
