Wemos mini D1 - radar

Kui ööd on pimedad siis väike valgus abiks on, et leida tee tualetti
Komponendid:
1. Wemos mini D1
2. Radarsensor RCWL-0516
3. Toide, (tel. laadia)
4. Installatsiooni materjalid

Wemos  wifi sigmaal -> Server MQTT - node red
programm node redis (kui kaua sonoff ON / OFF)
Node red - MQTT -> Sonoff - valgusti

RCWL-0516 <-> Wemos D1
VCC              -   5V
G                 -   GND
OUT             -   A0

wemos digipin pin andis stabiilselt HIGH ?
Töötab kui kasutada analoogsisendit: liikumine 1024, vaikus 9-10

Tsüklisse 100 ms viivitus
kui 5 x input > 20 siis tuvast. liikumine -> MQTT

* Node red
kui sisendis radar-1 on signaal ->   siis  saada msg.payload =1           -> sonoff kontakt ON
                                              oota 3 min saada msf.payload = 0     -> sonoff kontakt OFF
