Live Temperature and Humidity Monitoring over Internet using Arduino and ThingSpeak

Humidity and Temperature are very common parameters for measuring at many places like farm, green house, medical, industries home and offices. We have already covered Humidity and Temperature Measurement using Arduino and displayed the data on LCD. In this IoT project we are going to Monitor Humidity and Temperature over the internet using ThingSpeak where we will show the current Humidity & Temperature ...

Humidity and Temperature Measurement using Arduino

Humidity and temperature are common parameters to measure environmental conditions. In this Arduino based project we are going to measure ambient temperature and humidity and display it on a 16x2 LCD screen. A combined te mperature and himidity sensor DHT11 is used with Arduino uno to develop this Celsius scale thermometer and percentage scale humidity measurement project. In one of my previous project, I h ...

Even the humidity & temperature sensors can be „3G“

Even the actual series like SHT1x and SHT2x belong to a top in this segment. Forthcoming series SHT3x (SHT30, SHT31 and soon also SHT35) addresses mainly those of you, requiring maximum accuracy even in limit values (humidity below 10% and above 90%), miniature dimensions and ultra low power consumption. So a main difference of a new SHT31 compared to SHT21 is, that a typical +-2% is maintained in a whole r ...

How to Set Up the DHT11 Humidity Sensor on an Arduino

Because of their low cost and small size, DHT11 humidity and temperature sensors are perfect for lots of different DIY electronics projects. Some projects where the DHT11 would be useful include remote weather stations, home environment control systems, and agricultural/garden monitoring systems. The DHT11 is a digital sensor that lets you easily get relative humidity and temperature readings in your projec ...

Humidity sensor using 8051

This project is about a simple humidity sensor based on 8051 microcontroller. Humidity sensor is also called hygrometer. This circuit can sense relative humidity (RH)  from 20% to 95% at an accuracy of 5%. The humidity information is displayed on a 16×2 LCD display. A relay is also provided which is set to be active when the humidity crosses a certain trip point. The circuit is mains operated and it is very ...

HDC1000 temperature and humidity sensor breakout, with Arduino library!

Some time ago I came across a new chip from TI, the HDC1000. It’s a temperature and humidity sensor with I2C interface and requires little to no additional components. It comes in an 8BGA package: we can all agree it’s pretty small. Some of the peculiar characteristics of this chip are that it has a DRDYn pin which goes low any time there is a new reading from the chip (so you can precisely time your reques ...

HSM-20G temperature & humidity analog sensor + Nokia5110 LCD

Temperature and humidity measurement are always a nice addition to hobbyist projects. In my previous post, I’ve discussed the DHT11 sensor, which is capable of measuring both temperature and humidity. They are digital sensor and provide calibrated outputs with temperature and relative humidity. I’ve also demonstrated how to interface with Arduino and display it on 1602 LCD. Unlike DHT series, HSM -20G is an ...

WeatherShield1

WeatherShield1 description: The WeatherShield1 is able to read temperature, pressure and humidity values from the environment. It's equipped with a microcontroller that manages sampling and performs moving average on the last 8 samples. It's connected to the Arduino board though a synchronous bidirectional serial protocol similar to what was implemented in the MM5450 LED driver. WeatherShield1 specification ...

SHTC1 – humidity and temperature from a pin head

Miniature calibrated humidity and temperature sensor Sensirion SHTC1 is usable even in space - limited applications. Really miniature dimensions and a low price are main benefits of new calibrated sensors SHTC1 from production of company Sensirion. If you ever tried well known sensors series SHT2x, probably you´ve been surprised by their small dimensions (3,2x3,2x2mm). However the new sensor SHTC1 shifts di ...
