- Mon Jul 20, 2015 9:14 am #23715 anyone have hinys/suggestions as to why i'd be getting negative humidity value?

NodeMCU 0.9.6 build 20150406 powered by Lua 5.1.4
Humidity: -1%
Temperature: 3 deg C
Temperature: 37 deg F
> Humidity: -1%
Temperature: 13 deg C
Temperature: 55 deg F
Humidity: -1%
Temperature: 16 deg C
Temperature: 60 deg F

using the fpmdht.lua and dht.lua scripts...

also just got this:

> PANIC: unprotected error in call to Lua API (error loading module 'dht' from file 'dht.lua':
not enough memory)

(but i might have been trying to run init.lua too much?)

these are my files:

dht.lua : 2410 bytes
init.lua : 3014 bytes
----------------------------
Total file(s) : 2
Total size : 5424 bytes

Total : 52961 bytes
Used : 6275 bytes
Remain: 46686 bytes

???

thanks

ps - i'm using ESPlorer v0.2.0-rc2

i'm really new to programing/MCUs, so have no idea what "panic" means, or how bad it is???

(it sounds bad!)

- Fri Jul 24, 2015 7:27 am #24156 Read my FAQ as per below which explains what panics are how you can avoid them

Please see my Developer FAQ for Q&A on nodeMCU Lua before asking a question here that's already been answered. This and the other official documentation should be your first reference for developing Lua Apps

i just updated to July NodeMCU firmware and it works even LESS than it did before...
