LM35 temp sensor, sensitive to radiation or?
I got a bunch of LM35 sensors (3-pin) from Aliexpress and have some trouble with them reporting to high temperature readings. When connected to my breadboard with 15cm cables I had "normal" readings 20-21C. Now when I'm assembling a wemos D1 mini with a OLED in a tiny box I get 26C even with the sensor 2cm outside and with a heat shield (alu-foil and electrical tape). Anyone knows if this sensor is sensitive to e.g. wifi signals or just IR from the esp8266?
