Description
A module made by SparkFun, has a 4-channel NDIR sensor (nondispersive absorption in the infrared range), due to the fact that each channel has a different field of view, it allows not only to detect the presence of human, but also to determine the direction in which he/she moves. The current of each of the 4 sensors is measured in picoamperes. Reading the PIR is in the range of from -200 (when it detects nobody) up to 1500 (when a person stands in front of the sensor). The sensor communicates using the I2C interface. It is equipped with the Qwiic connector.
Pins
AK9753 module communicates using the I2C interface. The board has two connectors of Qwiic type, allowing for the communication via appropiate cables and holes for self-soldering of five goldpin connectors, pitch of 2.54 mm - strap is not included, it can be purchased separately.
| Pin | Description |
|---|---|
| SCL | Clock line of the I2C bus. |
| SDA | The data line of the I2C bus. |
| 3.3 V | Supply voltage is 3.3 V. |
| GND | The ground of the system. |
|
INT |
The external interrupt, the sensor sends a signal after the finished measurement (optional output) |
