How to Set Up the DHT11 Humidity Sensor on an Arduino

circuitbasics.com has a new tutorial on how to interface DHT11 humidity sensor to Arduino board. Sample code is provided

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.

Intel(r) Quark(tm) micrcontroller D2000 based Environmental sensors board

Sergey Kiselev designed and built an Intel Quark D2000 micrcontroller based Environmental sensors board:

This is a fairly small (51 x 51 mm) board, equipped with a low power Intel Quark D2000 microcontroller, and several sensors (accelerator, temperature, humidity, atmospheric pressure), as well as a mikroBUS compatible header and a Grove compatible connectors, that can be used to connect additional sensors, memory, or radio modules. The board can be used to monitor the environment conditions, and store or transmit the data to a remote system for further processing.

Sensor IC gives accurate RH and temperature from 2x2mm outline

161109edne-ams_pp_ens210_rgb

ams’ ENS210 sensor module features temperature measurement accuracy of ±0.2°C over the entire range 0°C to 70°C; the device also outputs relative humidity measurements on its I²C interface, enabling, ams says, portable and connected smart home devices to improve performance and implement new features. By Graham Prophet @ edn-europe.com:

The ENS210 is an high performance digital output sensor which monolithically integrates one relative humidity sensor and one high-accuracy temperature sensor. The device is encapsulated in a QFN4 package and includes an I²C slave interface for communication with a master processor.

Calendar- Time – Humidity and Temperature Arduino LCD display

FOAHQ08IR80Z9XV.MEDIUM

Jordan Kreindler shows us how to build a Battery Saving LCD display that is a able to show Time, Date, Humidity and temperature using DHT22, RTC3231 and Arduino.

The power saving mode here is what sets this Instructable apart from other examples showing day of the week, month, day of the month, time, humidity, and temperature. It is this capability that allows this project to be run from a battery, without the requirement for a “wall wart”.

Mare shares his sensor board based on MS5637 HDC108. He writes:

This is another small module to measure air pressure, temperature and humidity. Two sensors are on-board: MS5637 and HDC1080. Microcontroller is small cortex M0 in TSSOP-20 housing from STM: STM32F070CxP. The SN65HVD72DGKR provides RS485 interface functionality with half duplex mode. Voltage regulator, reverse polarity protection and some LED indicators are provided on-board. Complete module is 10x55mm, produced on single-sided PCB, easily producible in every home lab with proto-PCB capability.

New Ultra-Small Digital Humidity Sensor: Simplicity Meets Proven Performance

Sensirion_Humidity_SHTW2_300dpi

Sensirion, the world’s leading manufacturer of humidity, temperature and flow sensor solutions, presents its second generation WLCSP (wafer-level chip-scale package) humidity sensor: the SHTW2. The SHTW2 humidity sensor comes in a flip chip package – an established technology that represents one of the simplest and smallest possible ways of packaging a semiconductor chip and results in a tiny footprint of 1.3 x 0.7 x 0.5 mm3. The SHTW2 also pioneers a new category of ultra-small humidity sensors suitable for applications with the tightest space constraints.

The SHTW2 is based on Sensirion’s CMOSens® Technology, which offers a complete sensor system on a single chip with a digital I2C interface. The sensor is fully calibrated and covers a humidity measurement range of 0 to 100% RH and a temperature measurement range of -30 to 100 °C, with a typical accuracy of ± 3% RH and ±0.4 °C. The operation voltage of 1.8 V and the low power consumption make the SHTW2 perfect for integration in consumer electronics that run on the tightest power budgets, such as mobile phones, wearables and Internet of Things (IoT) applications. With the industry-proven quality and reliability of Sensirion’s humidity and temperature sensors, and constant accuracy over a large measurement range, the SHTW2 offers an unprecedented price-performance ratio. Tape and reel packaging and suitability for standard SMD assembly processes ensure the SHTW2 is ideal for high-volume applications.

The new digital SHT3x humidity sensor series takes sensor technology to a new level. As the successor of the SHT2x series it is determined to set the next industry standard in humidity sensing. The SHT3x humidity sensor series consists of a low-cost version with the SHT30 humidity sensor, a standard version with the SHT31 humidity sensor, and a high-end version with the SHT35 humidity sensor. The SHT3x humidity sensor series combines multiple functions and various interfaces (I2C, analog voltage output) with a applications-friendly, very wide operating voltage range (2.4 to 5.5 V). The SHT3x humidity sensor is available in both large and small volumes.

LED Weather Forecast using Raspberry Pi

FJFLPYYIN943NGB.MEDIUM

AughtNaughtZero @ instructables.com posted his latest project, a LED matrix visualizing data from a weather website such as temperature, pressure, humidity, wind speed etc.

This project utilizes a 6 x 16 matrix of RGB LEDs to visualize a weather forecast pulled from the Weather Underground API. A Raspberry Pi runs a python program designed to fetch weather forecast data from the API at regular intervals, parse the data into temperature, pressure, humidity, wind speed, chance of precipitation, and weather condition arrays, and then colorize and display that data across the LED matrix.
