Have you tried a Google search with the word "schematic" after the phrase you have in your question? I found within 30 seconds. It might not be exactly what you want but you should be able to work out the differences. Susan
Interfacing pic microcontroller with DHT11: Interfacing pic microcontroller with DHT22: The following two videos shows the simulation of digital humidity and temperature sensor DHT11 and the sensor DHT22 using ISIS Proteus software. These simulations are an interfacing of pic18F4550 with (...)
The following video shows the interfacing of pic16F877A microcontroller with 1602 lcd display and DS1307 real time clock and dht11 digital humidity and temperature sensor. The ds1307 uses I2C protocol to communicate with the microcontroller and the dht11 uses One-Wire protocol. The results are displayed on the lcd display. The circuit (...)
Hey there, I've been trying to interface a DHT11 sensor to a pic18F4550 and coding with xC8 compiler. Actually I've modified it from a website. I've successfully loaded a hex file into the MCU but the LCD only displays zero humidity and zero temperature. I've checked and my circuit has no problem. The DHT11 sensor is also (...)
I am a new learner. I have built temperature and humidity indicator using pic 16F877a (LM35 +SH20). I Have following two problems. 1) If I program to read only Temperature or only humidity it shows correct. But when I select Temperature + humidity - Both shows erratic reading ( RA1 and RA2). Request to suggest (...)
i need a program for humidity sensor(dht 11) code to interface with arm microcontroller
Hi guys, I'm currently working on a humidity project. I'd bought the "SN HMD MOD" (HR202) sensor , The sensor is basically consists of 4 pins (Vcc, GND, AO & DO). May I know what is the formula or equations to calculate humidity ? Full pic coding & explanation will be much appreciated :)
I am trying to make a system which measures Temperature and humidity, so I Choose SHT75 sensor. Have a look at this link:- The problem is that, What is this RH linear and RH True. I am confused, because Proteus is giving RH line
You may try to search for conveniable forum - - - Updated - - - I want to know how interfacing a resistive type humidity sensor to a microcontroller,I have a separate oscillator which also is connected to the other input of the pic.This oscillator frequency changes (decreases)when I load the beans which are the one I want
Hello here is example of this code for SHT-71. It is written for AVR but complete source can be downloaded so i think it will not be big problem to adapt functions to pic. You should only change PIN configuration functions but it is C compiles also..
Check with another sensor. Check this If there is more humidity it will give 4V for 80K resistor. pass some steam to increase the humidity. Datasheet says CAUTION IMPROPER HANDLING Do not remove the
My circuit is constructed as below. I'm a new beginner in programming. Desperately need help for the programming of this system. I have modified coding from similar project, but it keep on getting syntax error. Need help in modifying the AVR code for HSM20G into pic code for HSM20G. Facing syntax error in rx part. 70113
Have you measured the humidity oscillator frequency with and oscilloscope before and after connecting it to the pic ?
My project is wireless sensor node for monitoring indoor air quality. The sensor that i used are humidity and temperature sensor.. I have a pic16F877-20/P. This pic act as micro controller for my project. I want design a project of "wireless sensor node" =hardware of the (...)
hi sherazi just go here although it is in pic basic but at least give you an idea to do CRC for sht sensor Regards Fragrance
Hello everybody! I am building for my graduation project a wireless weather station. I am using pic 16f877 and I am building the project using Mplab. So far I managed to display the temperature using LM35 and pressure using MPX4115 on a 3310 nokia humidity I want to use a
I'm trying to build a project green house controller using a HCZ-J3A humidity sensor, i've been searching through lots of code for this but i'm having problems finding c code that works. Admittedly i will probably have to do some tweaking, but the only code i seem to come across is the SHT11 for an 80c51 chip which doesn;t really help. Can anyone p
i am attaching a vb screen shot which shows the temperature and humidity taken as 14 bit and 12 bit respectively. It also shows the communication between the microcontroller and sht10. The info is passed to pc thru serial communication. Each line is one full set of communication. R stands for com reset. s stands for transmission start s-f is
check this is a project done by Jody. A temp (DS1620) and a humidity (HS15p) sensor wich displays the readings on a Hitachi based LCD using pic 16F876A It includes a ziped file, codes, PCB, circuit and Gerbers. and this
I am presently working on moisture measurement and will need the SHT7x humidity sensor to design an electrical circuit. What pic has been proven good for the use of this sensor. I will also need program code for a display in an LED. Kingsley
hi.. I'm an engineering faculty undergraduate, and new to this field. i m using HCH-1000 Capacitive humidity sensors for my project. now I'm facing a problem to connect it with pic. i would like to know that how to interface this sensor with pic micro controller. could you please suggest me a circuit (...)
Hi to all, I am designing a humidity sensor circuit using a humidity sensor from china. Datasheet of that sensor is also in their language:|. But without those knowledge i am designing sensor circuit that I've placed my resistance dependent humidity (...)
Hello all, I need your help regarding this topic. I have recently bought this sensor and I need to interface it. Did anyone manage to attach the SHT11 humidity sensor to his circuit? I want to interface the SHT11 with a pic and and an LCD. If someone can, is it possible to attach the schematics (...)
Hi All, Is there a seperate formula I should use to get the pic to read my humidity sensor? There is a Vout formula in the datasheet... But is that the one I need to use? Thanks for any help. Amal
Hi every body, I want to connect pic microcontroller to a digital humidity-tremprature sensor SHT11 through a 100 meter distance wire. the sensor communicates through 1 serial clock and 1 serial data in a manner like i2c but it is not. the serial data is bidirectional. both signals are TTL. How can i do that without loosing
hi, I'm want to measure indoor humidity and temperature. For that i'm using SHT11 sensor. In website i can only find pic and C to program SHT11. Can anyone help me to program my sensor in Pascal ? Many many thanks before =)
hi, I'm want to measure indoor humidity and temperature. For that i'm using SHT11 sensor. In website i can only find pic and C to program SHT11. Can anyone help me to program my sensor for AT89S52 ? Many many thanks before =)
Hi all I have successfully interfaced an HT11 temperature & humidity sensor to a pic, but comparing the readings with other thermometers I have always too much temperature (i.e. 25 C vs 21 C real) and too low humidity (25% vs 35% real). I have soldered HT11 on a 8 pin DIL socket, and I think it's not affected by other (...)
