If you want to start making your own PCB's to make your own breakout boards or entire boards I would suggest looking into a product called PCB FAB-In-A-Box which runs about $150. I wasted a lot of time on that and on finding software online that gave accurate readings. I2C Address: 0x70. Would this work if I had it submerged in a in a dish of water to see when the water evaporated. I tried reconditioning it for a day in a plastic bag with a saturated salt solution, and now it reads 43.5%. The programming skill is all about communication and code. /CA 1.0 ready to connect the BME280 3-in-1 humidity sensor, measuring humidity, air pressure and ambient temperature, and the BMA400 ultra-low power . Connect your screen, mouse and keyboard to your Raspberry Pi. /Pages 3 0 R Simply unplug the USB from the Raspberry Pi (connected to the Pico) and plug in to your power bank charger or USB power adapter. We set the retail price where it is because of our calculated cost to build it. In the same terminal from Step 3, enter the following commands to build your UF2 file.

Blue is temperature and orange is humidity. about 7 years ago >> I think the 'minimium load' spec in the datasheet means minimum resistance, which is slghtly confusing as it could be misinterpreted as the device requiring a load. Stand-alone operation and seamless integration into the BMS with BACnet MS/TP and CAN bus networks. You can change the temp variable from 25 degrees Celsius to any desired value to see how it affects the Relative Humidity (RH%). Boot your Raspberry Pi. Sensors, Meters, and Gas Monitors Brochure (pdf - 6.51 MB) Place your Pico board on your breadboard. Maybe the 4030 is cheaper from their supplier? Belimo gas monitors provide: Building expansion and tenant improvements are a constant challenge. The datasheet doesn't have an "absolute maximum ratings" section, but 500uA looks like the most it can manage for the whole device, not just the load. Temp and Humidity are always zero: Adjust the timing in line 156. if (count > 46). You spend more time diagnosing and troubleshooting technical issues than moving on to the next project. The exceptionally small size in a robust DFN housing enables integration into challenging designs while meeting the highest reliability demands, as demonstrated by the JEDEC JESD47 qualification.
