Hardware Install

Prepare the following hardware equipments
■LinkIt One Development Board（includes GPS、WiFi antenna） x 1
■G3 PM2.5 sensor x 1
■DHT22 Temperature Humidity Sensor Module x 1

Assemble the battery of LinkIt One, GPS and WiFi Antenna ( The battery is lithium battery, please purchase the item by yourself.)
Refit the first, second, fourth fifth wiring on the G3 PM2.5 Sensor （which are purple, orange, green）into the Dupont connector（The package had complete the refit）　
Then on the G3 PM2.5 sensor:
Plug（Purple）into the 5V pin on LinkIt One,
Plug（Orange）into GND pin, and plug the fifth wiring（green）into RX pin
Connect（Blue）into Tx pin

Connect the Grove Temperature Humidity Sensor Module to the Grove Dupont connecting wire, and plug the first wiring（Yellow）into D2 pin, and plug the second wiring（White）into D3 pin（Actually you won't use this wire, so it doesn't matter if you plug this one）, and plug the third wiring（Red）into 3V3 pin（It was supposed to use 5V pin, but since it's being used by the PM2.5 sensor, so change into using 3.3 V, this sensor also support 3.3V voltage）, and plug the forth wiring（Black）into GND pin.

Complete the installation of the hardware, then you can switch the sensor and antenna into your favorite relative positions, you can also add the suitable cover.

If using Apple Cell phone, you may download MQTT Tester/Client (need to pay fee), and set the MQTT server as gpssensor.ddns.net, Port number to 1883, Topic is LASS/Test/PM25, then you can receive all the Field Try message immediately
The data references for the sensor this time please read LASS - App List and Sensor information

Usual Questions and answer

The suggested method of start the machine：
If it crush, the light TX and RX will discontinuous flickering, this might lead to the possible known Wifi problem, but it also might be the problem of Power on reset. So the suggestion is, when you start it up, plug the USB, then use the BAT power supply location to wait for all the lights go out, and switch back to the USB power supply location. Start it up by following these steps will not cause the crush for now.
