So we could basically use infrared sensors to see the health of our plants?
We do all the time. The NASA landst mission has been detecting in the infrared since it's inception, and currently collexts 30 m pixels about every 15 days. Likewise the sentinel mission is collecting similar wave bands and I want to say it has more frequent procession? Maybe 10 days?
Also, most modern drones that are for doing things like crop health will have a natively 4 channel sensor gathering blue, green, red, and near infrared imagery. Sometimes they'll even throw in multiple near infrared channels.
Back when I was flying drones for this we would run either 6 channels, or a 5 channel system with an upward looking sensor for calibration.
