Sharp Dust Sensor (GP2Y1051AU0F) with Temperature and PM2.5 Monitoring Board + Free Cable

Description:

The support model of the demo evaluation board is GP2Y1051AU0F. The demo evaluation plaque has been written to MCU and no other programming is required. After USB, it is displayed directly. The power supply is 5 V voltage. Connect the USB cable to the mobile power or to the USB port to power on. Some USB power instability software may be a bit biased, but it does not affect the use.

Display value:

1) 0 - 50 : air quality is excellent

2) 50 - 100 : air quality is good

3) 100 - 130 : air quality is light pollution.

4) 130 - 170 : air quality is moderate pollution.

5) 180 - 250 : air quality is a heavy pollution.

6) greater than 250 : air quality is serious pollution.

Screen interface:

1) P 50 for PM2.5

Err1: the PM2.5 sensor is not connected.

2) C 20 represents that the temperature is 20 Celsius.

Err2: the temperature sensor is not connected or has other faults.

3) On board 2 Led, they blink every 2 seconds, and they will not synchronize blinking.

4) The button board is currently not functional. second development for developers.

Note: There is already a PM2.5 detection program and a temperature display inside the PCB that you receive.

PM2.5 shows 8 seconds, the temperature shows 1 second, electoral screen.

The levels of PM2.5 appear from 0 (air is the worst, the faster the number, and vice versa) until the final number is stable.

Description of the component:

1) Digital display of the tube [4 Red]

2) 4 independent buttons

3) A temperature probe J1.

4) A PM2.5 sensor interface.

5) A serial port 2.54 row.

6) A port-back download program, convenient for users.

7) Pilot light 2 can be used for setting PM2.5 and temperature, and can also be used for other purposes.

8) I/O Port Output 2-USB side-can be used for PM2.5 or temperature detection for port output IO signal.

9) Single chip model: STM8S103F3P6.

10) LED pilot light 2 for instructions.

Serial port output parameters:

1) Baud rate: 2400 bit / s:

2) One byte is sent for every 10 ms, with a total of 7 bytes, in which the check = vOut (h) + vOut (l) + VREF (H) + VREF (L):

3) Data transmission format:

Data processing:

The received data is calculated according to the formula, and the output value is obtained: vOut = (vOut (h) * 256 + vOut (l) / 1024 * 5.

For example:

Output (h) = 0x01, converted to Decimal In 1:

VOut (l) = 0x3a, converted to Decimal En 58;

VOut = (58) 1 * 256 + / 1024 * 5 = 1. 533 v.
