product main pin function
VIN: power input positive pole (3.0V-5.5V DC), external 100nF ceramic capacitor filter is required to prevent voltage fluctuation interference
GND: power ground, common ground with the main control system to reduce noise
SCL: I²C clock line (open drain output), external 4.7kΩ pull-up resistor to VIN, maximum bus length ≤ 30cm
SDA: I²C data line (open drain output), external 4.7kΩ pull-up resistor to VIN, support standard/fast mode (up to 400kHz)
PWM : temperature data PWM output pin (optional mode), duty cycle corresponding to temperature value (to configure register to enable)
ADR: I²C address select pin (floating = 0x5A; VIN = 0x5B) for multi-device bus expansion
