The AM2305B is a high-precision digital temperature and humidity probe sensor with an operating voltage of 3.3 to 5.5V DC. It can measure temperature from -40°C to +80°C with an accuracy of ±0.5°C at 25°C and a resolution of 0.1°C.
The AM2305B is a high-precision digital temperature and humidity probe sensor with an operating voltage of 3.3 to 5.5V DC. It can measure temperature from -40°C to +80°C with an accuracy of ±0.5°C at 25°C and a resolution of 0.1°C.
Similarly, it can measure relative humidity from 0% to 99.9% RH with an accuracy of ±3% RH at 25°C and a resolution of 0.1% RH. It also offers excellent repeatability and hysteresis characteristics, ensuring consistent and reliable measurements.
It communicates with a microcontroller or other devices using the single-bus protocol, thus using only 3-wires.
