The Optek ADPD2212ACPZ-RL is a light-to-digital ambient light, infrared, and ultraviolet sensor. This optoelectronic device offers high sensitivity measurement in the range of visible to ultra-violet light. The sensor provides a digital output, in the form of a voltage which can be interpreted using a microcontroller interfaced with the module. The module also has an on board photodiode, metal oxide film resistor, and filter.

The ADPD2212ACPZ-RL’s application field includes visible spectrum (wavelength 400 nm to 700 nm) light sensing, as well as infrared (wavelength 800 nm to 1200 nm) and ultra-violet (wavelength 200 nm to 400 nm) light detection. Having high sensitivity and fast response time, the device is well suited for light detection in low light environments. Allowing for adjustable sensitivity and companding functions, this module is a great option for daylight sensing, motion detection, security systems, and other lighting applications.

The heart of the ADPD2212ACPZ-RL is the PIN photodiode, which works by capturing the light energy and converting it into a current. This current is then amplified by an amplifier/coil driver and converted into a voltage signal which is then sent to a microcontroller. The on board amplifier/coil driver is adjustable in order to accommodate different lighting conditions and therefore extending the light sensing range. Additionally, companding function enables the user to set the module’s control settings in order to increase the range of the module.

In addition to the PIN photodiode, this optoelectronic device utilizes a metal oxide film resistor which controls the amount of current flowing into the photodiode. It also consists of a filter which is used to eliminate noise and to ensure a consistent amount of light received by the photodiode. The filter is adjustable and allows the user to tweak the sensitivity of the module and limit the sensitivity to certain spectral regions.

The ADPD2212ACPZ-RL is a great option for ambient light, infrared, and ultraviolet sensing applications due to its high sensitivity and fast response time. With adjustable control settings and companding functions, this module ensures accurate and consistent light measurements even in dim lighting conditions. The module is easy to use and provides an intuitive interface for the user. Whether you’re looking for light sensing in low light environments or motion detection, the ADPD2212ACPZ-RL is a great solution for any application where light sensing is needed.
