Sensor outputs only 65535 as the reading

[varunhr]

Hi i recently bought a chirp I2C soil moisture sensor V2.7.4 and i hooked it up to Arduino Uno Like this Uno Chirp 5V/3.3V----- VCC(Tried Both) Gnd---- GND SDA -----SDA(10k Pullup) SCL------ SCL(10k Pullup)

My Code is this

include

void writeI2CRegister8bit(int addr, int value) { Wire.beginTransmission(addr); Wire.write(value); Wire.endTransmission(); }

unsigned int readI2CRegister16bit(int addr, int reg) { Wire.beginTransmission(addr); Wire.write(reg); Wire.endTransmission(); delay(20); Wire.requestFrom(addr, 2); unsigned int t = Wire.read() << 8; t = t | Wire.read(); return t; }

void setup() { Wire.begin(); Serial.begin(9600); writeI2CRegister8bit(0x20, 6); //reset }

void loop() { Serial.print(readI2CRegister16bit(0x20, 0)); //read capacitance register Serial.print(", "); Serial.print(readI2CRegister16bit(0x20, 5)); //temperature register Serial.print(", "); writeI2CRegister8bit(0x20, 3); //request light measurement Serial.println(readI2CRegister16bit(0x20, 4)); //read light register delay(1000); }

My Serial port output is this

Hi,

How long if your cable? Also, please write directly to me - mic at wemakethings net. Please send me your order number, we will sort it out.

Hi, Sorry for the delay in response. The sensor worked properly after some solder touchup on the Crystal Oscillator. Thanks for your support.
