Yes, it is possible to use an XBee module to capture the value of a DHT11 digital sensor, but not directly. The DHT11 sensor communicates using a one-wire proprietary protocol, which XBee modules do not natively support.

Possible Solutions:

1. Using a Microcontroller (Recommended)

   • Connect the DHT11 to an Arduino, ESP8266, or another microcontroller.

   • Read the sensor data using the microcontroller.

   • Transmit the data via XBee UART (Serial Communication) to another XBee module.

2. Using XBee I/O Line Passing (Not Suitable for DHT11)

   • XBee DIO (Digital I/O) pins can only transmit single-bit values (HIGH or LOW).

   • The DHT11 outputs multi-byte data (temperature & humidity), so it cannot be directly connected to an XBee digital input.

Why Can't XBee Read DHT11 Directly?

• DHT11 sends 40 bits (5 bytes) of data, but XBee’s digital input only supports single-bit data.

• XBee lacks the required timing precision to decode the DHT11’s protocol.

Conclusion

To capture DHT11 data using an XBee module, you must use a microcontroller (e.g., Arduino) to read the sensor and send the processed data via UART (Serial) to the XBee for wireless transmission.
