Hardware required The Bolt Wifi module 3 female to male wire Temperature Sensor: LM35 sensor Connections Connecting the LM35 sensor to the Bolt Step 1: Hold the sensor in a manner such that you can read LM35 written on it. Step 2: In this position, identify the pins of the sensor as VCC, Output…
This project is not only an intelligent coffee machine with smartphone control but also allows you to graphically view the temperature trend. It can be controlled via Bluetooth or simply fill up with fresh water and the system starts automatically! Developed on Arduino Nano, it uses an ST7920 display, an HC-05 Bluetooth module, a Dallas…
This project aims to monitor the temperature and humidity in a room, through a compact and cheap device, powered via USB and which sends data to our smartphone through WiFi communication. The circuit consists of an ESP8266 module, a DHT22 temperature and humidity sensor and a 3.3V voltage regulator. The ESP8266 module will connect to…
During the pandemic, people are being asked to have temperature checked at any local market or grocery store, which is usually done by another person. This can be a risky do to person to person interaction. In order to reduce this risk, we have developed a Temperature Access Point, which automatically detects people and invites…
Do you ever suddenly get the chills, so you check the temperature inside your room to make sure you’re not paranoid but then realize you don’t have any way to check? Or when the weather station’s predictions just seem too good to be true, so you double check the forecast for the nearest major…
Build a cloud weather station dashboard to visualize your ESP32 or ESP8266 sensor readings from anywhere in the world. You’ll see your sensor data displayed on gauges and on a table. The ESP32 or ESP8266 will make an HTTP POST request to a PHP script to insert your data into a MySQL database. More info
Since I am a man of science and I like data to know if something is actually working, I wanted to put my knowledge of IoT and electronics to good use and create an IoT Terrarium monitor. The plan was to build a sensor based system that could monitor temperature, humidity, and soil moisture from a simple yet…
Measure wind, rain, temperature, humidity, and light in remote locations using ThingSpeak, Particle, and the Sentient Things IoT Node. This project describes the latest generation of a weather station used by the ThingSpeak team at MathWorks (see ThingSpeak Weather Station & Data Analysis for an earlier version). This weather station provides the following improvements: Optional solar…
If you are in trouble with hot temperatures you can’t miss this DIY gadget, an Arduino-powered buzzer and led alert hat. While temperature increases leds change temperature from green to red and when it’s very hot a buzzer begins to play. More info
A small jewel capable of detecting atmospheric pressure and temperature, designed for the construction of weather stations or applications where it is important to know these parameters, such as air mass meters and altimeters. Let’s try it with Arduino. We know Omron for the many industrial sensors it has produced and continues to…
The Raspberry pi hat, called Enviro+, comes from Pimoroni, which is pitching the add-on as a cheap alternative to expensive environmental monitoring stations. With an additional particulate matter sensor, the Pi-based air-monitoring device can be placed just outside a house. Without the additional sensor, it can be used to monitor indoor air characteristics. “Designed for…
