BME680 measures pressure, humidity, temperature and indoor air quality

The BME680 measures pressure, humidity, temperature and indoor air quality. by Bosch Sensortec:

BME680 is an integrated environmental sensor developed specifically for mobile applications and wearables where size and low power consumption are key requirements. Expanding Bosch Sensortec’s existing family of environmental sensors, the BME680 integrates for the first time individual high linearity and high accuracy sensors for gas, pressure, humidity and temperature. It consists of an 8-pin metal-lid 3.0 x 3.0 x 0.95 mm³ LGA package which is designed for optimized consumption depending on the specific operating mode, long term stability and high EMC robustness.

This is a small (17.9 mm x 10.3 mm) breakout board with Bosch’s BME280 pressure, temperature, and humidity sensor as well as AMS’ CCS811 digital gas sensor. The sensors work in concert to provide a complete measurement via I2C register reads of indoor air quality including temperature- and humidity-compensated estimates of equivalent CO2 concentration in parts per million (400 – 8192 ppm) and volatile organic chemical concentration in parts per billion (0 – 1187 ppb).

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”.

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.
