No need to stick your nose into a carton of milk anymore, you can build a digital nose with the ENS160 Gas Sensor,... ## Pricing - **Price:** $37.50 (inc GST) — $34.09 AUD, exc GST - **Quantity discounts:** 10+ $33.07 (exc GST) · 50+ $32.38 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Sep 01 and Sep 07. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA5606:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA5606:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description \*sniff\* \*sniff\* ... do you smell that? No need to stick your nose into a carton of milk anymore, you can build a digital nose with the ENS160 Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at [ScioSense](https://www.sciosense.com/products/environmental-sensors/digital-multi-gas-sensor/), with I2C interfacing so you don't have to manage the heater and analog reading of a MOX sensor. It combines multiple metal-oxide sensing and heating elements on one chip to provide more detailed air quality signals. The ENS160 is the replacement for the [popular, but now-discontinued CCS811](https://www.sciosense.com/products/environmental-sensors/ccs811/). It has similar functionality but does require all new driver code so be aware if you are updating from an original design with the CCS811 that some work is required to upgrade. The ENS160 has a 'standard' hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog voltage, and provides an I2C interface to read from. [ScioSense provides an Arduino library with examples of reading the four raw resistance values and also the TVOC and eCO2](https://github.com/adafruit/Adafruit_SGP40) and [a Python/CircuitPython library](https://github.com/adafruit/Adafruit_CircuitPython_ENS160) that can be used with Linux computers like the Raspberry Pi or Adafruit's CircuitPython boards. **Please note, this sensor, like all VOC/gas sensors, has variability, and to get precise measurements you will want to calibrate it against known sources!** That said, for general environmental sensors, it will give you a good idea of trends and comparison. Another nice element to this sensor is [the ability to set temperature and humidity compensation for better accuracy](https://github.com/adafruit/Adafruit_CircuitPython_ENS160/blob/main/examples/ens160_advancedtest.py). An external humidity sensor is required and then the RH% is written over I2C to the sensor, so it can better calibrate the MOX sensor reading and reduce humidity/temperature-based variations. Nice sensor right? so they made it easy for you to get right into your next project. The surface-mount sensor is soldered onto a custom-made PCB in the [**STEMMA QT** form factor](https://core-electronics.com.au/search?q=stemma%20qt%20sensor), making them easy to interface with. The [STEMMA QT connectors](https://learn.adafruit.com/introducing-adafruit-stemma-qt/what-is-stemma-qt) on either side are compatible with the [SparkFun Qwiic](https://core-electronics.com.au/catalogsearch/result/?q=qwiic) I2C connectors. This allows you to make solderless connections between your development board and the ENS160 or to chain it with a wide range of other sensors and accessories using a [**compatible cable**](https://core-electronics.com.au/search?q=stemma%20qt%20cable). [QT Cable is not included, but Adafruit have a variety in the shop](https://core-electronics.com.au/search?q=stemma+qt+cable) We’ve of course broken out all the pins to standard headers and added a 3.3V voltage regulator and level shifting to allow you to use it with either 3.3V or 5V systems such as the Arduino Uno, or Feather M4. ## Technical Details **ENS160 Features:** - Detection of reducing (VOCs) and oxidizing gases - Support for up to 4 independent MOX gas sensors - Integrated sensor measurement and heater drive control - Integrated pre-calibrated sensor fusion and Automatic Baseline Correction algorithms - Multiple IAQ outputs (TVOC, eCO2, AQI) - I2C and SPI interfaces, however please note the libraries do not support SPI interface. - <3 minutes warm-up - <1 hour start-up - High immunity to humidity and ozone - I2C address 0x53 cannot be changed Product Dimensions: 25.4mm x 17.6mm x 4.5mm / 1.0" x 0.7" x 0.2" Product Weight: 1.8g / 0.1oz ![RoHS 2 2011 65 EU Compliant](https://core-electronics.com.au/attachments/uploads/RoHS2_2011_EU.png)![RoHS 2 2015 863 EU Compliant](https://core-electronics.com.au/attachments/uploads/RoHS2_2015_EU.png) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/A/D/ADA5606-1.jpg)
