Things used in this project

Hardware components

nRF7002 Development Kit
Nordic Semiconductor nRF7002 Development Kit
×1
Texas Instruments TXS0108EPWR 8-Bit Bi-directional, Level-Shifting, Voltage Translator for Open-Drain and Push-Pull Applications
Is used to bidirectional level shift the 1.8v of the nRF7002 to 3.3v/5v for the sensors. It is also available as a breakout for your breadboard. It is used in the PlantController PCB.
×1
Grove - Relay
Seeed Studio Grove - Relay
Control the outlet of the plant led.
×1
Grove - Temperature, Humidity, Pressure and Gas Sensor (BME680)
Seeed Studio Grove - Temperature, Humidity, Pressure and Gas Sensor (BME680)
Measure temperature, humidity and pressure.
×1
Seeed Studio MOSFET for Arduino
Control the 12v fan via pwm.
×1
NF-A14 industrialPPC-2000 IP67 PWM
The fan provides a good airflow, can be controlled via pwm and has a IP67 rating, so it is protected against water splashes.
×1
Lights for growing plants
There are different types, from a single bulb to a whole array of lamps. Choose what suites you and your budget.

Seeed Studio Grove RJ45 Adapter
Connect the sensor over a longer distance with RJ45 cables.
×2
Network Cable, Cat5
Network Cable, Cat5
×1
MeanWell 2-channel built-in switching power supply 32W, 12V / 1A & 5V / 4A
This power supply provides 12v for the fan and 5v for the nRF7002. It actually has way too much power, so a smaller one could also be used.
×1
Cold appliance plug
Connect mains voltage to the power supply.
×1
Surface-mounted socket
To connect your plant grow lights.
×1
Ikea Milsbo Cabinet
Or some other cabinet or greenhouse.
×1
Plants
Of course... Best is to use plants which need a high humidity like tropical plants, not ex. cacti
×1
Nylon Standoffs 2.5M
To hold the nRF7002 in place.
×4
Machine Screw, M3
Machine Screw, M3
For the case (12x M3x18), to hold the power supply (2x M3x10) and the cold appliance plug (2x M3x10) in place
×16
M3 Screw Nut
For the case (12x) and the cold appliance plug (2x) in place
×14
