A Problem…
How can we help?
Reduce our consumption: only water plants & lawns when they need it
How do we know whenplants need watering?
Measure the moisture in the soil!
How?Measure its resistance to electricity.
What do we need?
• A way to measure the resistance of soil
• A computer
• A visual display / alarm
• An audible alarm
• Power
The solution – a soil moisture probe!
What you will be doing…
• Surface mount
• Through-hole
• Programming
• Troubleshooting
Safety…
• Lab rules are for safety
• Lab rules are enforced
• Work individually but in groups of two or three (buddy system)
What else do electrical engineers do?
Power Systems
Renewable Energy
Electronics
Embedded Systems
Robotics
Plus a lot more…
• Biomedical
• Telecommunications
• Mechatronics
• Networking
• Software
Let’s have some fun!
