Hi Team,
Design door locks, such as LDC3114, LDC1612, LDC1314, which one is more suitable or which model is recommended.
1. The product is powered by a 3V twist button battery, so this sensor needs to support low power consumption, with an average standby current not exceeding 50uA.
2. Allow sensors to operate periodically, with a cycle not exceeding 100ms.
3. Dirty and humid environments cannot affect the sensor, so inductive sensors are preferred.
4. The material of the metal lock tongue is two types: iron and stainless steel. When the lock tongue approaches and leaves the sensing area, it has two different output states for the system to recognize.
5. When the metal lock tongue is in the sensing area for a long time, it should not increase the power consumption too much.
6. This sensor has an interrupt output pin that can wake up the system when the state changes.
7. If the above conditions are met, a pure hardware sensor solution is accepted, but it can also be an I2C/UART/SPI interface sensor, with priority given to reliability and stability.
