Questions

How big is the Wireless temp sensor PCB?

It measures 94 × 68.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Wireless temp sensor use?

21 parts, built around the ATTINY13A-SSU, ESP-12F, AM2302 and DS18B20. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Wireless temp sensor KiCad files?

From the Akilesh-10/Wireless_Temperature_Sensor repository on GitHub, at the commit this page was made from: the board is wireless_temp_sensor/wireless_temp_sensor.kicad_pcb and its schematic wireless_temp_sensor/wireless_temp_sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Wireless temp sensor design in my own project?

Its repository states no licence, so its author keeps all rights: ask Akilesh-10 before reusing the design.
