A: Yellowing of amaranth may be caused by yellow leaf disease, bacterial disease, powdery mildew and insect pests. At the same time, the lack of trace elements and improper fertilization can also be caused. In addition, soil acidification is also caused by the yellowing of leaves caused by poor absorption of nutrients by crops. Disclaimer: Some articles on this website are transferred from the Internet.

Industrial
Laser Distance Sensor, we also call it secondary development laser distance
module, which support TTL level and CMOS. The laser range sensor can be widely
used in professional surveying, mapping, construction, robots, hunting arrows,
industrial monitoring and automated measurement applications in electricity,
transportation, etc. Our laser distance module supports data communication with
RS232, USB with a simple adapter. The results of laser distance sensor can be
evaluated with Arduino. We are always looking ahead, hoping we can make every
measurement simple in life!
