So, using a drill and a rasp I made several slots on the side panels on both the indoor and outdoor units. In order to have accurate temperature and humidity measurements the sides of the cases have to allow air to enter the case. For that purpose I used 8mm tick MDF board and using a circular saw, I cut all pieces to size. Next, I moved on with making the cases for the project. With this step done, now we can simply attach the components onto the pin headers of the PCB. Then I also inserted and soldered the capacitor and the pull-up resistor. In this way we can easily connect and disconnect the components when needed. I started assembling the electronics components of this project by soldering pin headers on to the PCB. The quality of the PCBs is great and everything is exactly the same as in the design. Nevertheless, after several days the PCBs have arrived. Note that if itвЂ™s your first order from JLCPCB, you can get up to 10 PCBs for only $2. If everything is all right then we can go on, select the properties that we want for our PCB, and then we can order our PCB at a reasonable price. Here we can simply drag and drop the Gerber file and once uploaded we can review our PCB in the Gerber viewer. Then we can order our PCB from JLCPCB, which is actually the sponsor of this video. You can check theВ EasyEDA project files of Arduino wireless weather station here. Once we finish the design here, we can simply export the Gerber file which is used for manufacturing the PCB. We can note that the same PCB can be used for both the indoor and the outdoor unit, only the Arduino board should be programmed differently.

In order to keep the electronics components organized, according to the circuit diagram I designed a custom PCB using the EasyEDA free online circuit design software. With this configuration the outdoor unit could run for around 10 days before the batteries discharge, because we transmit data periodically and in the meantime we put the Arduino to sleep mode, where the power consumption is only around 7mA. There is also a pull-up resistor connected to the DHT22 data pin in order the sensor to work properly.ДЄs for the power supply I used 12V DC power adapter for the indoor unit, and on the other side, for powering the outdoor unit I used two Li-on batteries producing around 7.5V. Right next to the NRF24L01 transceiver module there is a capacitor to keep the power supply to it more stable.
