Arduino Based IoT Garden Monitoring System

For Arduino, standard library for DHT-11 sensor is already available. The data from the sensor can be easily ready by calling read11() method of the DHT class. The LDR sensor is connected in a potential divider circuit and inputs a voltage at the analog input pin of the controller. The voltage is read and digitized using in-built ADC channel. The moisture sensor also has an analog output which ...

Reset Arduino on Power. - Microcontrollers - Arduino Forum

2015-12-28· After uploading a sketch Arduino IDE uses the DTR through a cap to automatically reset the 328P which is a great idea, but it omitted the power-on-reset. It should keep the cap on the reset pin. The problem is that if the reset pin has a capacitor, the DTR reset doesn’t work, because it’s a weak pull down and cannot fully discharge the cap on the reset pin.

PIR motion sensor + counter / How to reset ... - Arduino Forum

2021-05-06· Hi Guys, I'm new at this forum. I'm building a motion sensor for my front door. Got a Partical Photon with an Grove Shield and a Grove PIR Motion sensor. I'm checking the highs for movement, but the wifi chip on the Partical interfere every 2/3 minutes (1 high). Googled a lot about this, but couldn't find a solution (other than board with ethernet or a different sensor).
