hi all, have dht11 temp/humidity sensor, (datasheet: http://www.micropik.com/pdf/dht11.pdf) , temperature readings receiving inaccurate around 5 degrees. wanted know if inaccuracy due design of sensor or programming. have included program i've used.
the dht11 not accurate sensor, 5 degrees bad. have seen between 0-3 degrees off.
what might add constant offset temperature reasonable right.
the dht22 bit better, supports 1 decimal , negative temperatures.
the ds18b20 (which uses protocol) applications best price quality. ds not support humidity however.
