Which pressure sensor is suitable for DIY?

Question

Do it yourself

Tell me which pressure sensor is best suited for measuring inside car tires?
at this stage, you need to calculate the feasibility of this diy
, I don’t need super accurate sensors, so far I’ve only found BMP085 (150r) from the available ones, according to the declared characteristics, it can report that the pressure is 1 atmosphere or less, but I wanted somewhere 1.5-1.8bar.
if the final cost (4 sensors +433 or bluetooth) exceeds 3000r, it would be more expedient to buy a Chinese system with outdoor mounting.

Answer 1

The BMP085 is now obsolete and has been replaced by the BMP180 and BMP280. The second is more accurate, but much more expensive. Forget about 433 (bullshit) and bluetooth (expensive and difficult). Use NRF24L01 to communicate with the master, cheap and cheerful (there are even cheaper analogues). If you need a connection with a computer, then you can install the ESP8266 ESP on the master, it has its own MK, so it can very well be the master itself.
Of course, the purchased system will be cheaper and more reliable, they are not designed to save
