Use it to build your own weather station or perform experiments. ## Pricing - **Price:** $23.50 (inc GST) — $21.36 AUD, exc GST - **Quantity discounts:** 4+ $20.29 (exc GST) · 12+ $19.23 (exc GST) · 50+ $18.16 (exc GST) ## Availability & dispatch - In stock, ships same business day if ordered before 2PM (Australia/Sydney). - We can dispatch 114 today, and up to 500 more in 6–42 days. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE07503:1` (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/CE07503:1.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 The PiicoDev® Atmospheric Sensor allows you to easily measure barometric pressure, humidity, and temperature. Use it to build your own weather station or perform experiments. Better still, you can connect to this sensor using PiicoDev adapters and cables - no soldering is required to connect the PiicoDev Atmospheric Sensor to other devices in the PiicoDev family. *This device may ship with a protective film covering the ASW switch. Carefully remove this film before attempting to set the switch.* **Features** - Measure temperature, pressure and relative humidity - PiicoDev connector, compatible with Qwiic and STEMMA QT (3.3V only) - Address Switch quickly changes the device address without soldering. - 2.54mm breakout for breadboarding/prototyping - Manufactured and [supported](https://core-electronics.com.au/contacts/) in Australia by Core Electronics **Getting Started Guides** - For [Micro:bit](https://core-electronics.com.au/tutorials/piicodev-atmospheric-sensor-bme280-quickstart-guide-for-microbit.html) - For [Raspberry Pi Pico](https://core-electronics.com.au/tutorials/piicodev-atmospheric-sensor-bme280-quickstart-guide-for-rpi-pico.html) - For [Raspberry Pi](https://core-electronics.com.au/tutorials/piicodev-atmospheric-sensor-bme280-raspberry-pi-guide.html) **Technical Specifications** - Address: 0x77 (ASW off - default) or 0x76 (ASW on). - Two unique addresses allow two devices to operate on the same I2C bus - The BME280 measures: - -40 to +85°C - 0 to 100% Relative Humidity - 300 to 1100 hPa - Temperature accuracy: ±0.5 °C from 0-60 °C - Breakout connector: 3.3V SPI interface, 5V tolerant I2C interface (with pull-up resistors to 3.3V) - Dimensions: 25.4x25.4mm - Mounting Holes: 2x M2.5 **Resources** - [Hardware Repo](https://github.com/CoreElectronics/CE-PiicoDev-Atmospheric-Sensor-BME280) - [Schematic](https://github.com/CoreElectronics/CE-PiicoDev-Atmospheric-Sensor-BME280/raw/main/Documents/schematic-piicodev-atmospheric-sensor-v10.pdf) - [Example code](https://github.com/CoreElectronics/CE-PiicoDev-BME280-MicroPython-Module) - [Mounting Guide](https://core-electronics.com.au/tutorials/piicodev-mounting-guide.html) - [BME280 Sensor Datasheet](https://core-electronics.com.au/attachments/uploads/bme280.pdf) Also available are [PiicoDev Starter Kits](https://core-electronics.com.au/piicodev/kits.html) - level up your projects by learning how to use a wide range of modern sensors and outputs. ![PiicoDev Atmospheric Sensor BME280](https://core-electronics.com.au/media/bannerslider/p/i/piicodev-atmospheric-sensor.jpg) ## Guides for this product - [PiicoDev Atmospheric Sensor BME280 - Raspberry Pi Guide](https://core-electronics.com.au/guides/raspberry-pi/piicodev-atmospheric-sensor-bme280-raspberry-pi-guide/) - [PiicoDev Atmospheric Sensor BME280 - Raspberry Pi Pico Guide](https://core-electronics.com.au/guides/raspberry-pi-pico/piicodev-atmospheric-sensor-bme280-quickstart-guide-for-rpi-pico/) - [PiicoDev Atmospheric Sensor BME280 - Micro:bit Guide](https://core-electronics.com.au/guides/micro-bit/piicodev-atmospheric-sensor-bme280-quickstart-guide-for-microbit/) - [Raspberry Pi Pico with LoRaWAN and The Things Network - Makerverse LoRa-E5 Module - Transmit Weather Data into IoT](https://core-electronics.com.au/guides/wireless/lora-pico-the-things-network/) ## Videos for this product - [PiicoDev Atmospheric Sensor BME280 - Raspberry Pi Guide](https://core-electronics.com.au/videos/piicodev-atmospheric-sensor-bme280-raspberry-pi-guide) - [PiicoDev Atmospheric Sensor BME280 - Micro:bit Guide](https://core-electronics.com.au/videos/piicodev-atmospheric-sensor-bme280-microbit-guide) - [PiicoDev Atmospheric Sensor BME280 - Raspberry Pi Pico Guide](https://core-electronics.com.au/videos/piicodev-atmospheric-sensor-bme280-raspberry-pi-pico-guide) - [Weatherproof LoRa Environmental Monitor - Makerverse LoRa-E5 and Pico Project - The Things Network and DataCake](https://core-electronics.com.au/videos/weatherproof-lora-environmental-monitor-makerverse-lora-e5-and-pico-project-the-things-network-and-datacake) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/p/i/piicodev-atmospheric-sensor-bme280-with-switch.jpg)
