I have ultrasonic sensor (sensor
1) connected to an ESP8266 and a Raspberry PI on the same WIFI network connected to another ultrasound sensor (sensor 2). When the distance detected by the sensor 2 is less than 30 cm, a movie starts on the RPI. I want that if a person passes in front of sensor 1 and then in front of sensor 2 the movie should not start. I want to use MQTT.
Dear employer,
I am a graduate of the Cisco IoT: Connected Things course in which I worked on a project that required linking a NodeMCU module with Raspberry Pi using MQTT protocol. I also worked on various mechatronics projects that included using ultrasonics for different applications.
Regarding your project, I will connect each ultrasonic to a topic of its own then when the Raspberry Pi detects information in both topics then the movie will stop. That will get the job described in the project description done but I will assist you any other requirements. I look forward to hear from you soon and wish you the best of luck.
Best regards,
Ahmed Nasr
