Hello friends, I hope you all are doing great. Today, I am going to share the new AHT20 Sensor Library for Proteus V1.0 . The AHT20 is the small I2C temperature and humidity sensor that has replaced the DHT11 in many new designs: it is more accurate, it answers on the I2C bus in a fraction of a second, and it costs about the same. It often comes on a combo board with the BMP280 pressure sensor, which makes a complete weather station on four wires. Now you can build and test those projects in Proteus, with the blue AHT20 module and the purple AHT20 + BMP280 module . Behind the parts sit our own models , not parts that show a number. The AHT20 answers the Arduino exactly as its datasheet says: the status byte with the busy bit, the 80 ms measurement, the 20-bit values and the CRC-8. On the c ...
Hello friends, I hope you all are doing great. Today, I am going to share the new HX711 Load Cell Library for Proteus V1.0 . The HX711 and a bar load cell are the heart of nearly every Arduino scale: kitchen scales, parcel scales, beehive scales, filament spool scales and force testers. The load cell turns the weight into a few millivolts, and the HX711 turns those millivolts into a 24-bit number. Now you can build the whole weighing chain in Proteus, with the green HX711 module and the aluminium load cells of 1, 5 and 20 kg . Behind the parts sit our own models , not a part that shows a number. The load cell is a real Wheatstone bridge in the analog simulation, unbalanced by the weight you put on it. The HX711 drives the bridge from its 4.3 V regulator, converts the bridge voltage like th ...
