the dht shows a lot how to use it letting us know it on the serial monitor but few projects are making it known with lcd I2C and that's why in this tutorial I will teach you how to do this
The dht I explain it here
vcc to positive
gnd to negative
dates to pin 2
this is with 3 PIN DHT.
el dht se muestra mucho como usarlo haciéndonos saberlo en el monitor serial pero pocos proyectos hay haciéndolo saber con lcd y por eso en este tutorial les enseñare a hacer esto
El dht lo explico aquí
vcc a positivo
gnd a negativo
data a pin 2
este es con DHT DE 3 PINES
EXPANDED TECHNICAL DETAILS
Environmental Monitoring Dashboard
This practical project provides a real-time visual of room temperature and humidity, essential for climate control and laboratory monitoring.
- 1-Wire Digital Protocol: The Arduino communicates with the DHT11 sensor using a specialized single-wire timing pulse. The firmware decodes the pulse-width patterns into 40 bits of humidity and temperature data.
- Refreshed-UI Data Update: The Arduino updates the 16x2 LCD every 2 seconds. The firmware includes a "Safe Range" indicator; if humidity exceeds 70%, the LCD displays a "HUMID" warning.
Prototyping
- Web Editor validated: The sensor's complex timing logic was optimized in the cloud editor to provide a rock-solid data stream with zero CRC errors.
