Hi I am using Honeywell pressure sensor to measure pressure of air in a pipe. for this have to use I2C Communication with pic PIC16F1787 I attached circuit for this is my Circuit is perfect ? Help me out in programming side i used I2C protocol for Honeywell air pressure sensor's Digital I2C address is 0X49. to reading data from sensor the program flow are 1st master send data to slave >send start condition > send Digital address (0X48) > stop condition 2ndly read data from slave means slave response to master > start condition > Digital address (0x49) > than reading data moreover for same program for RTC DS1307 slave i am getting data from RTC with RTC address in same program but i am not even getting garbage value for Honeywell sensor for same I2C pin and configuration so is there any programming change for this particular sensor is there any additional change for this sensor for I2C protocol programming Data sheet of Honeywell sensor is https://sensing.honeywell.com/honeywell-sensing-zephyr-digital-airflow-10-slpm-300-slpm-datasheet-008268-5-en.pdf please help me out -- Thank You Er.

> Honeywell pressure sensor The 12th digit of the sensors order code is 2, 3, 5, 6 or 7? Mismatching "7-bit vs. 8-bit" I2C address format used?
