Once the cement has cured, fill the box with soil. Remember to heat seal the end of the Outlet pipe before making a hole in it for the dripper. The dripper is used to regulate the water coming out of the pipe so that the water does not flow out of the...
I'm currently working on different improvements to the sensor: I added LoRaWan to the sensor already (using the SPI bus) and I'll add a bigger update on this in the next weeks. Now that the days are becoming shorter in Germany, the visibility of the...
We use IOT Cricket WiFi module to make a sensor which will be sending a temperature value every 30 seconds to our system. It will run on a battery so we can stick it anywhere at home or a garden. Later you can also use Cricket to build various...
The use of VL53L1 TOF sensor is really interesting. But what makes it different from many competing proximity sensing technologies? (Ultrasonic, Sharp IR angle, LIDAR...) Beyond the fact that it allows a detection up to 300 inches, a 60Hz refresh rate...
Learn your sensor's baselineSince it seems that different types of moisture sensors have different outputs, not to mention different soil types and plants require different amounts of water, it's a good time to figure out what a nominal value would be...
With the bottom electrode in place, measure 5cm up from the top of the copper and mark the wall of the container, this will be your soil fill level. Flip the cathode(upper electrode) out of the way and add some water, about 500ml in my case. I...
The cherry on top of the cake would definitely be a calibration screen mode. Imagine, the transparent plastic cover is off and you push a small calibration push-button. The regular screen statistics disappear and you get a full 32x24 pixels thermal camera...
Introducing Pet Pot - Not Your Ordinary Planter! Have you ever wanted a plant that communicates with you? Well, that's exactly what Pet Pot is all about! Pet Pot is not just an ordinary planter; it's a smart planter with a unique personality. Pet Pot...
This project uses the W1209 thermostat board. What I did was make a few small modification to the board: remove the 20k smd resistor next to the sensor connector,throw the sensor in the junk box,add a 10k resistor across the sensor connector (underneath...
After Uploading the code , you can blow next to the sensor .If the led is not lighting up, you need change the sensor sensitivity (reduce Sensitivity) by rotating the potentiometer .Here in this video I am demonstrating how the prototype works....
The image here show the design of the full leg system, prepared in Lego Digital Designer. The list of components (BOM) are in the file Leg System.xlsx. The building instructions can be found in the Lego Digital Designer Leg...
Design printed circuit board (PCB), I was used ,,Sprint-Layout" software. Exported to Gerber files. PCB was made https://jlcpcb.com To create this NodeMCU ESP12 weather station shield you will need: NodeMcu Lua CH340G/CH340/ ESP8266 Wireless WIFI Internet...
The Automatic Room Light Controller using Arduino and IR Sensor is a simple project, where the lights in the room will automatically turn on upon detecting a human motion and stay turned on until the person has left or there is no motion. Working...
Today we'll be creating a remote controlled satellite weather station using a Raspberry Pi, a temperature sensor and a RockBLOCK. The envisioned application would be a weather station in a really remote location (i.e. outside of mobile/cellular coverage)...
While the sensor Arduino was being programmed, the buoyancy control Arduino also had to be programmed to control the stepper motor and communicate with the sensor Arduino. Thus, the buoyancy control Arduino was programmed to take a depth measurement,...
