Hologram%20dash
Hologram Global IoT SIM Card
×1
Adafruit 12V Solenoid Valve
Or use preferred alternative
×3
i2c Soil Moisture Sensor
×1
12V DC Fluid Pump
Or use preferred pump
×1
Rain Sensor
We upgraded this to a Seeed Studio Water Level Sensor more recently: https://www.seeedstudio.com/Water-level-switch-p-565.html
×1
12002 04
Breadboard (generic)
Optional, or use solderable prototype board
×1
Mfr 25frf52 10k sml
Resistor 10k ohm
Pull up resistors for i2c bus and a pull-down resistor for the Water Level Switcg
×3
Texas Instruments ULN2003a
Darlington Array for the Solenoid Valves and DC Pump
×1
12V 2A DC Power Supply
Or alternative based on your choice of DC pump / solenoids, make sure it can provide enough current
×1
STMicroelectronics L78S05CV 5V Regulator
This is only used for the i2c Soil Moisture sensors (see in the story below). Or alternative - 2A is more than necessary for this project. Follow the datasheet for your chosen regulator, this one needs a 0.33µF tantalum at input, and recommends a 0.1µF ceramic at output

Software apps and online services:
Hackster
ThingSpeak API
Hand tools and fabrication machines:
3drag
3D Printer (generic)
Optional, for water distribution parts, tube adaptors etc.
Lasercutter
Laser cutter (generic)
Optional, we made our planter from laser cut acrylic
09507 01
Soldering iron (generic)
Also, general soldering tools, wire strippers, micro side cutters, solder, etc
