This function will split a number into two partaccording to times. @paramnum the number will be split @param integer the integer part @param decimal the decimal part @param times how many times of the real number (you should use 10 in this case) @return 0 if num is positive, 1 if n...
How to use DHT11 and DHT22 Sensors TheDHT11andDHT22Sensors are factory calibrated and output serial data and hence they are highly easy to set it up. The connection diagram for this sensor is shown below. As you can see the data pin is connected to an I/O pin of the MCU and a 5K...
IOTA MQTT与DHT11传感器设备教程说明书 IOTA TUTORIAL 30mobilefish.com Send DHT11 data to the tangle using ESP-01S, MQTT and MAM v1.0.0
When you have a DHT11 sensor, you will be able to get the temperature and humidity of your environment. Given that, this post shows how to use ESP32 development board to read temperature and humidity from a DHT11 sensor. Arduino IDE, DHT sensor library for ESPx, DHT11, ESP32, Internet...
In this Arduino Tutorial we will learn how to use the DHT11 or the DHT22 sensor for measuring temperature and humidity with the Arduino board. You can watch the following video or read the written tutorial below for more details. Table of contents ...

We show how to wire the device up, and then how to code the Arduino. The data is passed from the Arduino to python. We then create a live 3D thermometer model that updates as the temperature changes. On the arduino side, this is the code which we use: Arduino 1 2 3 4 5 6 7 ...
How to use DHT11 Sensor The DHT11 Sensor is factory calibrated and outputs serial data and hence it is highly easy to set it up. The connection diagram for this sensor is shown below. As you can see the data pin is connected to an I/O pin of the MCU and a 5K pull-up resistor ...
