batrec_nodemcu_1.yaml

#------------------------------
#-- batrec_nodemcu_1.yaml
#-- Petit code pour monitorer plusieurs batteries branchées en série
#-- La mesure se fait avec un ADC/i2C et NodeMCU blindé
#-- Afin de pouvoir lire des tensions >2.048V, il y a un diviseur résistif R1/R2 de 270kR/12kR pour arriver à 42V -> 1.78V !
#-- Il y a donc un facteur de correction de 24x environ avec une plage de mesure de 0V à 42V
#-- location: garage
#-- zf230506.1152
