Tekneka 7228 is a large LED temperature humidity display monitor that comes with an external sensor, it can measure ranges from -40 to 85ºC / 0 to 100%RH. The large 17.2-inch LED screen gives you a better view up to a 40m distance range.
Long visual distance from 15~75m. Sensors with high accuracy & stability. Possibility to display year, month, day, temperature simultaneously. Deviation can be calibrated by buttons. Memory for 43 000 readings.
Temperature and Humidity. When you need to accurately and easily monitor humidity and temperature, only the most reliable, precise LED displays will do. Our state-of-the-art LED signs are built to the highest possible standards so they won’t let you down.
These Large Digital LED Displays combine Temperature and Humidity on two separate displays in a single case with an integral 4~20mA dual input sensor or a dual 0-10Vdc input signal.
In this instructable, I have used the DHT11 Temperature & Humidity sensor & Arduino UNO to display the current temperature & humidity readings into a 16 x 2 LCD Display. Alongside, I have also created a 3-LED setup which indicates 3 sets of temperature readings (cold, hot, extreme).
Product Code: HTM-823. Quantity: The HTM-823 large display is ideal for areas where the temperature and humidity of the environment need to be clearly visible. The bright LED is visible in dimly lit areas and can be seen from a distance of up to 30 metres, with a viewing angle of 90º.
This time it’s a simple temperature and humidity display, and so far it’s working pretty well. It’s built around an Arduino Nano and uses a DHT22 sensor. The display is an extremely cheap MAX7219-based four-module LED matrix (130x32mm), and its brightness is controlled by a capacitive touch sensor (11x15mm). In this case, everything runs ...
