Adafruit just announced Adafruit CH552 QT Py and this board ranks in the top part of my weird tech list. The MCU used in this is a WinChipHead (WCH) CH552 has an E8051 Core. with 16 kilobytes of flash memory but only about 1.25 kilobytes of RAM, and the most weird thing about this it has […]

Humidity sensor using 8051


https://www.electronics-lab.com/humidity-sensor-using-8051/

by circuitstoday.com: This project is about a simple humidity sensor based on 8051 microcontroller. Humidity sensor is also called hygrometer. This circuit can sense relative humidity (RH) from 20% to 95% at an accuracy of 5%. The humidity information is displayed on a 16×2 LCD display. A relay is also provided which is set to be […]

Delay using 8051 Timer

The major component of this circuit is Microchip’s SST89E54RDA-40-C-PIE, which is a pin-for-pin compatible with typical 8051 microcontroller devices. It has a built-in timer used to produce accurate time delay. The light emitting diode (LED) is connected through the 330Ω resistor to indicate the time delay. The blinking LED switches ON for 1ms and switches […]

Distance Measurement using Infrared Sensor with ADC0804 & 8051 Microcontroller


https://www.electronics-lab.com/distance-measurement-using-infrared-sensor-with-adc0804-8051-microcontroller/

This project primarily consists of four units: Microchip Technology’s SST89E54RDA-40-C-PIE, a sensor unit, an ADC0804 ADC component and the LCD module. Along with detecting an obstacle, its exact distance is also calculated and displayed on a 16×2 LCD interfaced to the microcontroller. The IR receiver detects the IR radiations reflected by the object being measured. […]
