Waterproof DS18B20 Digital temperature sensor Resistor (Waterproof DS18B20 temp)
Description:

This is a pre-wired and waterproofed version of the DS18B20 sensor.  Handy for when you need to measure something far away, or in wet  conditions. While the sensor is good up to 125°C the cable is jacketed  in PVC so we suggest keeping it under 100°C. Because they are digital,  you don't get any signal degradation even over long distances! These  1-wire digital temperature sensors are fairly precise (±0.5°C over much  of the range) and can give up to 12 bits of precision from the onboard  digital-to-analog converter. They work great with any microcontroller  using a single digital pin, and you can even connect multiple ones to  the same pin, each one has a unique 64-bit ID burned in at the factory  to differentiate them. Usable with 3.0-5.0V systems.

The only  downside is they use the Dallas 1-Wire protocol, which is somewhat  complex, and requires a bunch of code to parse out the communication. If  you want something really simple, and you have an analog input pin,  the TMP36 is trivial to get going.

We toss in a 4.7k resistor, which is required as a pullup from the DATA to VCC line when using the sensor.

Specifications:

Cable specs:

  • Stainless steel tube 6mm diameter by 30mm long
  • Cable is 36" long / 91cm, 4mm diameter
  • Contains DS18B20 temperature sensor
  • If  your sensor has four wires - Red connects to 3-5V, Black connects to  ground and White is data. The copper wire is soldered to the wire  shielding
  • If your sensor has three wires - Red connects to 3-5V, Blue/Black connects to ground and Yellow/White is data

DS18B20 Technical specs:

  • Usable temperature range: -55 to 125°C (-67°F to 257°F)
  • 9 to 12 bit selectable resolution
  • Uses 1-Wire interface- requires only one digital pin for communication
  • Unique 64 bit ID burned into chip
  • Multiple sensors can share one pin
  • ±0.5°C Accuracy from -10°C to 85°C
  • Temperature-limit alarm system
  • Query time is less than 750ms

DC 5V Waterproof Ultrasonic Module Distance Measuring Transducer Sensor (waterproof ultrasonic)
Description:

This waterproof ultrasonic distance sensor is for those applications that are a bit more rugged! 25cm - 450cm sensing range.

We have used the HC-SR04 Ultrasonic Distance Sensor many times  and for many good reasons. It is pretty easy to use, it performs well, and it is very inexpensive. For collision avoidance robots or intruder detection, this sensor is usually all you’ll need.

However, using the HC-SR04 outside is a different story. It is a pretty fragile device and can easily be damaged by dirt, or even high winds. And, above all, it is not waterproof.

For these circumstances you can use this sensor, in more weathered states, even outdoors

Specifications:

Operating voltage: DC 5V
Total current work: 40mA
Acoustic emission frequency: 40khz
Maximum distance: 4.5m
Blind: 25cm

Wiring:
5V (positive power supply)
Trig (control side) RX
Echo (the receiver) TX
GND (negative)

Resolution: about 0.5cm
Angle: 70 degrees
Working temperature: -10 ~ 70 ℃
Storage temperature: -20 ~ 80 ℃

Product Features:

- small size, easy to use;
- low voltage, low power consumption;
- high accuracy;
- strong anti-jamming;
- integrated with wire enclosed waterproof probe, suitable for wet, harsh measuring conditions.

Application:

1 Horizontal distance;
2 obstacle avoidance, automatic control;
3 traffic control;
4 security, industrial control;
5 artificial intelligence, and research

Basic working principle:


(1) using IO port TRIG trigger location, to the high level signal of at least 10us;
(2) module automatically sends 8 40KHz pulse, automatic detecting whether a signal returns;
(3) on signal return, a high level is output through the IO port ECHO, the time duration of the high level is ultrasonic from launch to return. The test distance = (high level time * speed of sound (340M/S)) /2;
