Gesture Recognition Sensor Module(GY- PAJ7620U)
From Wiki
Introduction
PAJ7620U2 integrates the gesture recognition function and general purpose I2C interface into a single chip. PAJ7620U2 has build in proximity sensing function that is used to detect the approaching or leaving objects. The gesture information can be easily accessed by using I2C bus
Features
- Typical supply voltage ranges from 2.8V to 3.3V and I/O voltage is 1.8V~3.3V
- Nine gesture recognition (Up / Down / Left / Right / Push / Pull / CW / CCW / Wave)
- Gesture speed is from 60°/s to 600°/s in Normal Mode and 60°/s to 1200°/s in Gaming Mode
- Ambient light immunity: < 100k Lux
- Built-in proximity detection
- Flexible power saving scheme
- I2C interface up to 400 kbit/s, Pull-up voltage from 1.8V to 3.3V
- Ambient light noise cancellation
Introduction of Pins
VIN：Power Supply
GDN：Ground
SCL：I2C clock pin
SDA：I2C data pin
INT：Interrupt pin(Active low)
Principle
The PAJ7620U2 should be oriented as shown in Figure 4 for correct gesture detection
if rotate the gesture module, The direction of gesture detection interrupt flag mask(Register Bank 0,ADDR 0X41)and gesture detection interrupt flag(Register Bank0,ADDR 0X43)nedds to re-mapping.
Step 1: Connect the circuit:
| GY-PAJ762 | SunFounder Uno |
| VIN | 3.3v |
| GND | GND |
| SDA | A4 |
| SCL | A5 |
