Sensor Interfacing 8051

Sensor Interfacing 8051 - span class news dt jul 29 2018 span nbsp 0183 32 pir sensors are widely used in motion detecting devices this article is about interfacing a pir sensor to 8051 microcontroller a practical intruder alarm system using pir sensor and 8051 microcontroller is also included at the end of this article before going into the core of the article let s span class news dt jun 18 2016 span nbsp 0183 32 sensor interfacing in 8051sensor interfacing in 8051 slideshare uses cookies to improve functionality and performance and to provide you with relevant advertising if you continue browsing the site you agree to the use of cookies on this website the project is built to demonstrate working of lm35 temperature sensor interfaced with 8051 through adc0804 the lm35 series are precision integrated circuit temperature sensor produced output voltage o o1v per 1 176 of voltage change is linearly proportional to the.
temperature led interfacing to 8051 there are two ways which we can interface led to the microcontroller 8051 but the connections and programming techniques will be different this article provides the information on led interfacing with 8051 and led blinking code for at89c52 at89c51 microcontroller interfacing led to 8051 methods the ir interfacing shown below gives the analog o p and so for that there can be two ways to ir sensor with interface 8051 either this analog o p can be given to adc and then it is interfaced with 8051 this par is expalined on site go for the link interfacing pir sensor to 8051 the 8051 considers any voltage between 2 and 5v at its port pin as high and any voltage between 0 to 0 8v as low since the output of the pir sensor module has only two stages high 3 3v and low 0v it can be directly interfaced to the 8051 microcontroller
