Sensor H2S not respoding?
I test the H2S gas sensor, but it not responding. I use UART serial port protocol. I setup as the manual setup but I still did not get response from sensor. I use baud rate 9600, data bits 8, check bit 1. I try to communicate with sensor but no response. Also I preheating the sensor for 24 hours but remains same.
Any help how to get response from sensor to serial port communication?
Hi! Please dial the DIP switch SEL on the sensor to 1 and power on again, the sensor will use uart mode. The baud rate of the serial port in the sample code is 115200. May I ask what board are you using? Where are the TX and RX of the sensor connected to the board?jenna
