DHT11 - Humidity and Temperature Sensor

DHT11 - Humidity and Temperature Sensor The DHT11 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data.

Explore pir sensors for arduino |

NO, most likely this sensor won’t be sensitive enough, it is intended to detect Infrared Red emitted by human body, bees are too small. If you want to count the number of bees coming to the bee hive and possibly discriminate if they are coming in and getting out you should have better success with micro wave presence sensor, which with an Arduino and some a firmware will be able to detect ...

2 pir sensor >> 2x interrupt on arduino pro mini - Project ...

May 05, 2021· I want to make a portable pir (2x) sensor connected to arduino pro mini and than transmit some data ( via 433mhz transmitter ) to another arduino. To save power I would like to make arduino sleep and only be waken up by pir. The problem is I can’t make the code to work with two pirs on two interrupts. I was able to make it work with one pir. So my question is if it is doable (2 pirs on 2 ...

Arduino PIR Sensor Tutorial | PIR Motion Sensor with Arduino

Jan 12, 2018· The design of the PIR Motion Sensor using Arduino is very simple. The PIR Sensor Module has three pins: VCC, Digital Out and GND. Connect VCC and GND to +5V and GND respectively. Then connect the Digital Out Pin of the PIR sensor to the digital I/O pin 8 of Arduino. As we need to indicate the detection of motion by the sensor, connect a buzzer ...
