Sensors for hydroponics, aquariums and pools. Measure salinity, EC, TDS, pH, and ORP. IoT stuff.

If you are interested in CNCing your own PCBs and using pcb2gcode, we just released a new GUI for it. It has some nice features like project saving, paste and mask layer processing, and includes most available options.

Ever think "I wish creating a schematic could be done with code"? @atopile_io did and this is what they made. It's pretty cool.

We released a new Arduino library. It lets you use any LoRa hardware to create @home_assistant sensor devices.

We found a new-looking SHTx waterproof module on AliExpress and tore it apart to see how waterproof it really was.

We added a @AdafruitIO template and about 15 @adafruit sensors to our Embedded CopyPasta 🍝 app.

Automatically generate Arduino code for various platforms and sensors.

Ever notice that a lot of Arduino code is boilerplate?
- Find/download/#include library
- start class
- :begin() class
- loop()
- handle the data
Embedded CopyPasta 🍝 makes it easy to do all that automatically. Plus, it will make a PlatformIO project.

Followed up our ESPNow ->ESPHome component with a #lora -> ESPHome component.

Now you can make battery-powered LoRa sensors in @esphome_.

Interested in battery-operated @esphome_ sensors? We wrote a couple components using ESP-Now. Battery life estimators show it should live about 4000 hours on a tiny 260 mAh battery.
Also, the whole thing is just one line of YAML.

Here's a write-up of making a battery-powered #esphome/#homeassistant sensor device. It uses an SHT30 for temperature and humidity, but you could switch it to whatever you want. Complete with a nice #3d printed box to put it in.

Ever want to use a 10k NTC? Here's an option for you, an easy I2C sensor that uses the MAX6682 for 0.125 degree resolution. Any 10k thermistor will work.

Ever try to learn Fusion360 and make something useful? We did today, a probe holder. The cool thing about 3d printing is you can download the file and make it yourself.

[Microfire LLC @microfire_co]

Our conductivity, pH, and ORP sensors now have native external components in ESPHome. Make a fully-functional water monitor with just YAML. @esphome_ and @home_assistant make it easy to go from hardware to databases and graphs.

We added heat index and wet-bulb temperature estimations to our SHT3x library.

We were gone for a while, but now we're back. Our products are easier to use, come with Arduino and Home Assistant examples, and our 🌱 EC+pH Kit is currently on sale.

So that Daylight Saving Time legislation is pretty cool, but how bout switching to Celsius?

[Einthecorgi @Einthecorgi2]

It has been 0 days since I last had to do some silly stuff to deal with shortages.

[Mike @anothervariable]

Finished designing the enclosure. @FreeCADNews is pretty fun and straight forward.

Hooked up to the Aeroponics tower and ready to test.

UI preview coming within a week.

For the 0.00001% of people that are looking for a replacement for the out-of-stock everywhere ADG704BRMZ, the MAX4634EUB+ is a drop-in replacement. Same pins, same logic, same everything. 🧐

[Mike @anothervariable]

First time using @kicad_pcb. Pretty stoked it all fired right up, except for a small SSR footprint mishap shown in a pic below, but no biggie.

Huge thanks to Justin at @ufire_co for all his help and excellent product.

High Pressure Aeroponics Controll board.

To be honest, I had accidentally swapped the 008004 component with a piece of lint when placing it 😅
