  • Page 3: Overview

    Since the introduction of GP2Y1010AU0F, Sharp has released newer models such as GP2Y1014AU0F and GP2Y1026AU0F which offer improvements in design and function. Sharp GP2Y1026AU0F is a digital UART sensor featuring a built-in microcomputer (MCU) which handles some of the processing you would normally need to provide yourself such as offset calibration, temperature correction, LED pulsing, and averaging of data values to minimize noise.

    11501W90-6P-S-HF which should be compatible with the old JST connector. What this all means is if you have an old cable harness for GP2Y1010AU0F, the cable should work just fine with GP2Y1026AU0F as well. The following table and figure shows the pin assignments for GP2Y1026AU0F.

    The pulse drive circuit also helps to extend the lifetime of the sensor under continuous operation. Although the Sharp sensor has a RxD terminal, you don’t need to send it any commands in order to begin receiving serial UART data from the sensor’s TxD terminal.

    Arduino or else the upload will fail. Another option is to use Serial1 on Arduino Mega 2560 for communicating with the dust sensor. The GP2Y1026AU0F dust sensor outputs 1 byte every 10ms through its TxD terminal. According to the specification, it produces a 7-byte data frame as follows: Thus it takes 70ms to output a data frame which is equivalent to 14 frames per second.
