Thanks for your kindness!
Here is my code and I have problem at receiving motor speed(Mspeed) and switch function from Ubidots.
#include <DHT.h>
#define DHTPIN 2 // SDA pin setting
#define DHTTYPE DHT22 // DHT22 (AM2302) sensor type
DHT dht(DHTPIN, DHTTYPE);
// Motor control
int IN1 = 7;
int IN2 = 8;
int ENA = 6; // Motor speed control pin
int TempLimit = 30; // Temperature condition to run motor
int HumiLimit = 50; // Humidity condition to run motor
#define ssid "****" // Put here your SSID
#define password "****" // Put here your PASSWORD
#define id1 "*************" // Put here your Ubidots variable ID1 temp
#define id2 "*************" // Put here your Ubidots variable ID2 humi
#define id3 "*************" // Put here your Ubidots variable ID3 speed
#define id4 "*************" // Put here your Ubidots variable ID4 speed control
#define id5 "*************" // Put here your Ubidots variable ID5 switch
#define token "**************" // Put here your Ubidots TOKEN
void setup() {
// put your setup code here, to run once:
Serial.begin(115200);
Serial.println("\nModule Settings WiFi ESP8266");
pinMode(IN1,OUTPUT);
pinMode(IN2,OUTPUT);

sendCmd("AT+CWMODE=3", "Ap+Station Mode", 1000); // cmd AT+CWMODE=3: Sets the Wi-Fi Ap + Station Mode
sendCmd("AT+CWJAP=\""ssid"\",\""password"\"", "Successful WiFi Connection!", 5000); // cmd AT+CWJAP: Connects to an AP
sendCmd("AT+CIPMUX=1", "Enable Multiple Connections!", 500); // cmd AT+CIPMUX=1: Enable Multiple Connections
}
void loop() {
// put your main code here, to run repeatedly:
float dato1 = dht.readTemperature();
float dato2 = dht.readHumidity();
float Mspeed;
float Switch;
receive_D(Mspeed, Switch, 2);
send_D(dato1, dato2, Mspeed, 3); // The last parameter "3", is for choose the number of variables to send to Ubidots: (1-3)
//Motor control process
