HK7001 Digital Proximity and Ambient Light Sensor
Category:
Key words:
Ambient light distance sensor
Product Details
HK7001 is an integrated low-voltage ambient light and proximity sensor in a miniaturized leadless patch HLGA package with built-in infrared emitting LED and I2C communication interface. Its ambient light sensing function can provide reliable support for backlight brightness adjustment, and it also has infrared detection capability to realize proximity detection. For the convenience of the user, it can also be set to interrupt mode.
For ambient light detection, HK7001 can maintain linearity in the dynamic range of 0.01lux to 128klux, which makes it suitable for various lighting environments, whether it is in a bright environment under direct sunlight or behind dark glass, it can maintain normal operation. A special process was added to the production process to make the spectral response curve fit the human eye characteristics perfectly.
For proximity detection, users can easily configure the drive current of the infrared LED through the register. In addition, HK7001 also has a built-in noise cancellation circuit to effectively filter out other infrared interference in the environment.
The HK7001 integrates a well-designed temperature compensation circuit to make it have good temperature stability, and the internal refresh frequency can be maintained stably without external components. It can be put into standby mode by software control to save power consumption. The supply voltage range of the HK7001 is 2.7V to 3.6V.
