DHT22 measure wrong values #358

Closed fiurthorn closed 1 year ago

fiurthorn commented 2 years ago

using DHT22 from https://www.amazon.de/gp/product/B08NP8NR1J/ref=ppx_yo_dt_b_asin_title_o01_s03?ie=UTF8&psc=1. gives wrong values:

humidity := dht.NewWithPolicy(machine.GP15, dht.DHT22, dht.UpdatePolicy{})
t2, h, _ := humidity.Measurements()
temp2 = fmt.Sprintf("%d", t2/10)
hu = fmt.Sprintf("%d", h/10)
tinyfont.WriteLine(&display, &freeserif.Regular9pt7b, 40, 15, hu+" %", white)
tinyfont.WriteLine(&display, &freeserif.Regular9pt7b, 40, 30, temp2+"  C", white)
