Adafruit MPRLS Ported Pressure Sensor Breakout - 0 to 25 PSI (3965)

airport pressure = 29.8"Close as I need it to be, so the 0.007" is as close to zero as I can get, so I assume 0-25psi is a real range.

seems to work most of the time, sometimes it wanders off and has to be unplugged for a while. it's about the only pressure sensor I could find,

Successfully integrated into a Raspberry Pi used in pneumatic mast system. The outside diameter of the port is 0.1 inches. I installed the entire board into a section of PVC conduit and used an air tight connector to get the data out. Works well with Arduino and PI4J. All necessary information is on the Honeywell web site

It does the thing - it measures pressure.

La instalé con un ESP8266 y funcionó a la perfección.Luego con ESP32 y funciona, pero cada cierto tiempo da un brinco erróneo de lectura, no se si es por la velocidad del procesador o que la dirección fija que trae entra en conflicto con el Bluethooth u otra cosa, lo cierto es que no lo puedo usar. La dirección fija I2C no es algo bueno para quien hace un proyecto y trabaja con prueba y error.

It was easy to wire up and get working. The values jumped around a little bit, so it’s best to take an average of 5-10 readings quickly and use that as your output value. The problem is that it got *maybe* 2 hours of use before it stopped working. I2Cdetect won’t find it on the bus anymore, so programs won’t recognize it.Edit: dropped to one star. The second one I got lasted for about 10 minutes of use, then threw and error stating it had “Integrity failure”. These are junk.

great for getting familiar with this type of pressure sensor. Was able to write some I2C code and read pressure with no problem.
