Hello,

Sorry for my bad english, I have XC-0331 Wireless Ultrasonic Tank Level Meter which measure temperature and water level for tank. I want to decode the RF433 signal from the device.

I read a few signal ( example in attachment ) and decode them (long signal as 1 and short signal as 0). For start I just want to read temperature without water level.

I look on the PCB of device and the temperatrue sensor is NTC HT series. If I read value with arduino when temperature is 21 Celsius, the value is 473 .

Please help me if anyone see how can I read temperature.

Thank you in advance.

Best regards,

All of the data(0.69m) are 100% ?
